Why is weight different on different planets? An object's weight is dependent on its mass and how strongly gravity pulls on it. The strength of gravity depends on how far away one object is from another. That's why the same object weighs different amounts on different planets. Your weight is different on other planets due to gravity.
Why does the same object weigh different on different planets?
An object's weight is dependent on its mass and how strongly gravity pulls on it. The strength of gravity depends on how far away one object is from another. That’s why the same object weighs different amounts on different planets. It’s sometimes easier to compare planets using a measurement that isn’t quite so complicated.
How much does your weight change on other planets?
Your mass doesn’t change on other planets, but the gravity and size of those planets affect how much you weigh. So, your weight depends upon the gravity of the planet and your weight keeps changing based on planet gravity. The amount of gravity depends on the size of the planet.
Does your weight depend on the gravity of the planet?
So, your weight depends upon the gravity of the planet and your weight keeps changing based on planet gravity. The amount of gravity depends on the size of the planet. A small planet has less gravity and the larger planet has more gravity.
Why do we weigh more on smaller planets like Neptune?
This is why you weigh more on larger, more massive planets like Jupiter and less on smaller, less massive planets like Mars. The mass of an object depends not only on its size, but also its composition. Even though the planets Uranus and Neptune are nearly the same size, Uranus is less dense and has less mass, so your weight would be less.
Why do you weigh more on larger planets?
Planets and moons are very massive objects and have a very strong pull on other objects. This phenomenon is known as gravity. More massive objects have a stronger pull than less massive objects. This is why you weigh more on larger, more massive planets like Jupiter and less on smaller, less massive planets like Mars.
Why does weight change on different planets but not mass?
Your mass doesn't change on other planets, but the gravity and size of those planets affect how much you weigh. So, your weight depends upon the gravity of the planet and your weight keeps changing based on planet gravity. The amount of gravity depends on the size of the planet.
What happens to your weight on different planets?
This force of attraction between you and the Earth (or any other planet) is called your weight. If you are in a spaceship far between the stars and you put a scale underneath you, the scale would read zero. Your weight is zero. You are weightless.
Why does gravity affect weight?
This means that for a given gravitational field strength, the greater the mass of the object, the greater its weight. Weight is a non-contact force because gravity exerts its force through a field. An object does not need to be touching the Earth to have a weight.
Why does weight change on location?
A person can weigh differently at various place on Earth because of the fluctuations in Earth's gravity, according to a new high-resolution map. Gravity is often assumed to be the same everywhere on Earth, but it varies because the planet is not perfectly spherical or uniformly dense, researchers said.
Why would you weigh less on other planet than you do on Earth?
Planets that are less massive than Earth have less gravitational pull than Earth. Mars has less mass than Earth so if you were to weigh yourself on the surface of Mars – you would weigh a lot less. This is because there is less gravitational force to pull on you even though your body mass stays the same.
Why is your weight more on Jupiter?
Jupiter is a massive planet, the biggest in our solar system, and it has a stronger gravitational pull than Earth. In fact, its gravity is about 2.4 times as strong as Earth's. This means, if you weigh 40 kg (88 lbs) on Earth you would weigh 94 kg (207 lbs) on Jupiter.
Why do we weigh less on moon?
Mass of the moon is less than the Earth, therefore, the force of attraction is less. Mass of the moon is more than the Earth, therefore, the force of attraction is more. Mass of the moon is equal to that of the Earth.
What planet would you weigh 68 kg?
If you weighed 68 kg on Earth then you would weigh 25.6 kg on Mars. Since Pluto was demoted to a dwarf planet, Mars became the planet where you would weigh the least. Jupiter is the largest planet in our Solar System with the most mass.
How much would you weigh on Jupiter?
Because of Jupiter’s mass, you would weigh more on that planet than on any other one in our Solar System. If you weighed 68 kg on Earth then you would weigh 160.7 kg on Jupiter, over twice your normal weight. That is if you could actually stand on Jupiter’s surface, which is impossible because it is a gas giant, ...
What is Saturn known for?
Saturn is a gas giant best known for its planetary rings system. It is also the second biggest planet in our Solar System. Despite its mass though, the planet has a very low density and a lower gravity than Earth. If you weighed 68 kg on Earth, you would weigh 72.3 kg on Saturn.
Which planet is the smallest in the solar system?
Mercury is the smallest planet in our Solar System, but it is dense. Because Mercury is so small, it has very little gravity. If you weighed 68 kg on Earth, you would only weigh 25.7 kg on Mercury. Venus is very close to Earth in size and mass. Venus’ mass is roughly 90% of the mass of the Earth.
How much does Venus weigh?
Thus, it is no surprise that someone would weigh a similar amount on Venus. Someone who weighed 68 kg on Earth would weigh 61.6 kg on Venus. Mars is quite a bit smaller than Earth with only 11% of our planet’s mass.
Which is bigger, Uranus or Neptune?
Although Uranus is larger in size than Neptune, it has less mass and therefore less gravity. You would only weigh 60.4 kg on Uranus, if you weighed 68 kg on Earth. Neptune, the last planet in our Solar System, is a gas giant. If you weighed 68 kg on Earth, then you would weigh 76.5 kg on Neptune if you could stand on the planet’s surface.
Is weight different on another planet?
For one thing, your weight would be different on another planet, depending on a number of factors including the mass of the planet and how far you are away from the center of the planet. Before we start, it’s important to understand that the kilogram is actually a measurement of your mass.
How to weigh a planet?
The Short Answer: To weigh a planet, scientists need to know two things: how long it takes objects to orbit the planet and how far away those objects are from the planet. The time it takes an object to orbit a planet depends on its distance from the planet and the planet’s weight. In real life, we can’t pick up a planet and put it on a scale.
Why is gravity different from planet to planet?
If you were to step onto a scale on another planet, it would say something different than it does here. That’s because the planets weigh different amounts, and therefore the force of gravity is different from planet to planet.
How do scientists use gravitational pull as a scale?
In order to figure out how heavy a planet is, scientists need to know two things: how long it takes nearby objects to orbit the planet and how far away those objects are from the planet. For example, the closer a moon is to its planet, the stronger the planet will tug on it. The time it takes an object (whether it's a moon or spacecraft) to orbit a planet depends both on its distance from the planet and how heavy the planet is.
Why do scientists usually talk about mass rather than weight?
An object's weight is dependent on its mass and how strongly gravity pulls on it. The strength of gravity depends on how far away one object is from another. That’s why the same object weighs different amounts on different planets. It’s sometimes easier to compare planets using a measurement that isn’t quite so complicated. That’s why scientists and engineers often measure an object’s mass —how much matter the object contains—rather than its weight.
How much would you weigh on Jupiter if you were on Earth?
If, on the other hand, you were on heavy Jupiter, you would weigh a whopping 253 pounds!
What is the tug on a planet?
The heavier the planet, the stronger it tugs on nearby objects—like moons or visiting spacecraft. That tug is what we call gravitational pull.
What keeps the Moon in orbit around our planet?
Earth's gravitational pull is what keeps the Moon in orbit around our planet. Voyager 1 snapped this picture of Earth and the Moon from a distance of 7.25 million miles. Credit: NASA/JPL-Caltech
How does weight affect the universe?
Every object in the universe with mass attracts every other object with mass. The amount of attraction depends on the size of the masses and how far apart they are. For everyday-sized objects, this gravitational pull is vanishingly small, but the pull between a very large object, like the Earth, and another object, like you, can be easily measured. How? All you have to do is stand on a scale! Scales measure the force of attraction between you and the Earth. This force of attraction between you and the Earth (or any other planet) is called your weight.
What is the mass of a body?
The mass of a body is a measure of how much matter it contains. An object with mass has a quality called inertia. If you shake an object like a stone in your hand, you would notice that it takes a push to get it moving, and another push to stop it again. If the stone is at rest, it wants to remain at rest.
What does standing on a neutron star mean?
Standing on a neutron star makes you unimaginably weighty. Not only is the star very massive to start with (about the same as the Sun), but it is also incredibly small (about the size of San Francisco), so you are very close to the center and r is a very small number.
Why is the mass in the numerator?
The "r" below is the distance from the center of the planet. The masses are in the numerator because the force gets bigger if they get bigger. The distance is in the denominator because the force gets smaller when the distance gets bigger. Note that the force never becomes zero no matter how far you travel.
What happens when you double your mass?
If you double your mass, gravity pulls on you twice as hard. If the planet you are standing on is twice as massive, gravity also pulls on you twice as hard. On the other hand, the farther you are from the center of the planet, the weaker the pull between the planet and your body. The force gets weaker quite rapidly.
How does the force get weaker?
The force gets weaker quite rapidly. If you double your distance from the planet, the force is one-fourth. If you triple your separation, the force drops to one-ninth. Ten times the distance, one-hundredth the force.
Does weight attract other objects?
Weight is an entirely different thing. Every object in the universe with mass attracts every other object with mass. The amount of attraction depends on the size of the masses and how far apart they are.
Which planet has less mass?
Even though the planets Uranus and Neptune are nearly the same size, Uranus is less dense and has less mass, so your weight would be less. Distance also has an effect on the pull of gravity. You may have noticed that although the Sun is the most massive object in the Solar System, your weight isn't quite as much as you might think. ...
Which planets have a stronger pull?
The mass of an object depends not only on its size, but also its composition. Even though the planets Uranus and Neptune are nearly the same size, ...
What is the attraction of planets and moons?
The strength of this attraction depends on how massive the objects are and how far apart they are. Planets and moons are very massive objects and have a very strong pull on other objects. This phenomenon is known as gravity. More massive objects have a stronger pull than less massive objects.
Why is lead brick heavier than concrete?
This is because it contains more matter and is therefore more massive. All celestial objects in the universe with mass have a measurable pull on all other objects with mass. The strength of this attraction depends on how massive ...
Can we stand on the surface of the Sun?
Of course, we all know it is impossible to stand on the surface of the Sun. It would also be impossible to stand on the surface of the gas giant planets like Jupiter and Uranus, because they have no solid surface. But this demonstration does show how mass affects gravity and the weight of objects.
