What is the scientific word for how much an object weighs on a scale?
The scientific word for how much an object weighs on a scale is “mass”. In this book we will use the words “weight” and “mass” interchangeably, because both are used in everyday language. For example “I weigh 60 kg ” or “the car's mass is 1 tonne”.
What is a scale that has electronic devices on it like digital and LCD screens?
A scale that has electronic devices on it like digital and LCD screens. Calibration. This is process by which a scale is set in order to take accurate readings. Most analogue scales can become inaccurate when they are moved around, because they have moving parts inside that can shift if the scale is bumped or dropped.
How many soccer fields does Khuthele School have?
Khuthele School has two soccer fields. The grass need to be covered with fertiliser. A bag of 30 kg of fertiliser costs R 42,60. The school will need to buy 96 bags. How much will they pay for the fertiliser? How many kg will they buy altogether?

What is the procedure to determine body fat percentage?
Another technique is air displacement plethysmography . After undressing, you enter a computerized, egg-shaped chamber (called a BOD POD) that totally encloses your body. Once your body density is determined through your weight and volume, the machine uses this data to calculate your body fat percentage.
What does a bathroom scale measure?
Your bathroom scale may estimate your body fat as part of its various functions. Body fat scales use technology called bioelectrical impedance analysis (BIA). When you step on the scale, an electrical current passes through one leg, up to the pelvis, and down the other. Fat conducts far less electricity than the water and muscle you have in your body. So, when the scale picks up more resistance, it records more possible body fat.
How to measure body fat percentage?
1. Tape measure. A basic way to measure body fat percentage is by using a soft tape measure, like the kind you’d use for sewing, to record measurements of different parts of the body. You can also find tape measures specifically marketed as body fat tape measures, like these ones on Amazon.
What is hydrostatic weight?
Hydrostatic weight. Hydrodensitometry is a weighing method where you sit undressed in a chair that’s submerged in water. Your body density or weight under water is recorded as your body places a buoyant counterforce on the water and displaces it. The weight recorded can then be used to calculate your body fat percentage.
How to maintain a healthy weight?
Regardless of your body fat percentage, there are things you can do at home to maintain a healthy weight: 1 Make sure you get 150 minutes of moderate exercise (walking, cycling, water aerobics) or 75 minutes of vigorous exercise (running, swimming laps, playing sports) each week. 2 Carve out time for strength training two days a week. Try lifting weights, doing body-weight workouts, or doing yard work. 3 Eat a diet rich in whole foods, like fruits, vegetables, and whole grains. Skip over processed foods that contain empty calories with little nutritional value. 4 Keep your portion sizes in check, especially when out to eat. Restaurant portions tend to be much larger than single portions. 5 Discuss diet and exercise plans with your doctor. You may even consider asking for a referral to a dietitian to help you get on the right track with your goals.
What are the tools used to measure body fat?
Things like clothing, what you’ve eaten, and how tightly you pull the tape measure may also affect results. 2. Calipers . A skin-fold test is done using a tool called calipers to pinch different areas of your body and measure body fat.
How accurate is underwater weighing?
The percentage that it estimates should be within 1 percent of body fat for both adults and children.
What is the unit of measurement for weight?
What Is the Unit for Measuring Weight? The scientific, international standard SI unit for measuring weight is the "Newton.". In everyday use, the unit for mass, the pound (lb) or kilogram (kg), is used instead. Weight is defined as the force on an object due to gravity, while mass is the property of a body to resist acceleration by a force.
How many grams are in a kilogram?
The international standard SI unit for mass is based on grams (g). One kilogram is 1,000 grams. One ton is 1,000 kilograms. In the United States, people often use the pound as well. One pound is about 0.45 kilograms. ADVERTISEMENT.
What is the purpose of measuring body mass?
purpose: measuring body mass can be valuable for monitoring body fat or muscle mass changes, or for monitoring hydration level. equipment required: Scales, which should be calibrated for accuracy using weights authenticated by a government department of weights and measures.
How to improve reliability?
reliability: To improve reliability, weigh routinely in the morning (12 hours since eating). Body weight can be affected by fluid in the bladder (weigh after voiding the bladder). Other factors to consider are the amount of food recently eaten, hydration level, the amount of waste recently expelled from the body, recent exercise and clothing. ...
Why is body weight important in sports?
Body Weight. Body weight is commonly measured in fitness testing sessions. Measuring body weight in sports is important for assessing body composition and for monitoring changes in weight following diet and exercise.
Why does gravity cause weight?
Gravity causes Weight. An object's weight is how hard gravity is pulling on it. We think the weight is the same everywhere ... because we all live on the surface of the planet Earth! But in orbit it would not push on the scales at all.
What is the difference between mass and weight?
Mass is a measure of how much matter something contains. Weight is a measure of how strongly gravity pulls. Apparent Weight is a measure of downwards force. Force is measured in Newtons, not kilograms.
Why do people use "weight" and "mass"?
People often use "weight" to mean "mass", and vice versa, because Gravity is almost the same everywhere on Earth and we don't notice a difference. But remember .. they do not mean the same thing, and they can have different measurements.
Does the mass of an object change?
An object's mass doesn't change (unless you remove some!), but its weight can change. On the Moon the scales would wrongly show 16.6. for a mass of 100 kg. Because the pull of gravity on the Moon. is much less than on Earth.
Can scales be fooled?
Apparent Weight. But scales can be fooled ... because they measure a "downwards force" and don't know if it is gravity or some other force! Just jump up and down ( gently!) on your scales at home to see your apparent weight change, while your mass stays the same.
Is weight measured in kilograms?
Well, weight should not really be in kilograms! I have used "kilogram" so far because that is what you see on a pair of scales, but it is technically wrong to talk about weight in kilograms ... ... weight is a force ... ... which is measured in Newtons.
How many people edit wikihow?

What to do when an object is too light to find the weight?
If the object is too light to find the weight this way, you'll need to either decrease the friction at the pulley or at the fulcrum, or use lighter-weight materials for the balance and cups. ...
What is a ruler balanced on?
This can be a ruler balanced on an object, or a string over something with little friction with cups tied at both ends. ...
How to find the weight of an object?
While a scale is the most accurate way to find the weight of an object, you can get an approximation by using a handmade balance. To start, tie string to the top of 1 cup, then tie the end of the string to the top of another cup. Balance the middle of the string over a tall, solid object so the cups can hang freely.

How is the mass of the asteroid Mathilde calculated?
MASS of asteroid Mathilde was calculated by measuring gravitational perturbations in the course of the passing NEAR spacecraft.
What is the centripetal force?
The centripetal force is the Earth's mass times the square of its speed divided by its distance from the sun. By astronomically determining the distance to the sun, we can calculate the earth's speed around the sun and hence the sun's mass.
What is Newton's law of gravity?
Newton's Law of Gravitation states that every bit of matter in the universe attracts every other with a gravitational force that is proportional to its mass. For objects of the size we encounter in everyday life, this force is so minuscule that we don't notice it. However for objects the size of planets or stars, it is of great importance.
How does the gravitational force between the Earth and the Sun work?
The gravitational attraction between the Earth and the sun is G times the sun's mass times the Earth's mass, divided by the distance between the Earth and the sun squared. This attraction must be equal to the centripetal force needed to keep the earth in its (almost circular) orbit around the sun. The centripetal force is the Earth's mass times ...
How does an asteroid bend its path?
Just like a natural moon, a spacecraft flying by an asteroid has its path bent by an amount controlled by the mass of the asteroid. This "bending" is measured by careful tracking and Doppler radio measurement from Earth. Recently, the NEAR spacecraft flew by the asteroid Mathilde, determining for the first time its actual mass.
Who is Barry Lienert?
Barry Lienert, a geophysicist at the University of Hawaii, provides the following explanation. We start by determining the mass of the Earth.
