Mass (m) = 75 kg Mass (m) = ? Gravity (g) = 9.8 m/s/s Gravity (g) = 9.8 m/s/s Formula: F = mg Formula: m = F/g Substitution: F = (75 kg)(9.8 m/s2) Substitution: m = 490 N/9.8 m/s2 Answer: 735 N Answer: 50 kg 3. What is the force on a 1 kg ball that is falling freely due to the pull of gravity? Force (F) = Formula:
What are the forces acting on a block of 2kg?
A block of mass 2kg is acted upon by two forces: 3N (directed to the left) and 4N (directed to the right). What can you say about the block's motion?
What is the force acting on an object in free fall?
The definition of free fall states that the only force acting on an object is gravity. So if this is what you meant by “freely falling” then gravity will be the only force. In your case it will be 98.1 N downward.
What is the force of gravity acting on a 1 kg mass?
10NOn Earth, an object with a mass of 1kg will experience a force of 10N due to gravity, i.e. the weight of a 1kg mass is 10N.
What is the net force that acts on a 1kg freely falling object?
9.8 NAll objects placed upon Earth's surface will experience this amount of force (9.8 N) upon every 1 kilogram of mass within the object.

What is the force of a ball falling?
The gravitational force is an interaction between two objects with mass. For a falling ball, the two objects with mass are the Earth and the ball. The strength of this gravitational force is proportional to the product of the two masses, but inversely proportional to the square of the distance between the objects.
What is the net force acting on a 1 kg ball in free fall What is the net force if it encounters 2 N of air resistance?
What is the net force acting on a falling 1 kg ball if it encounters 2N of air resistance? 2), which is equal to 10 N. Air resistance is a force in the opposite direction to a falling weight so the net force acting on the ball is 10 N - 2 N = 8 N.
What is the force of a free falling object?
The motion of a free falling object can be described by Newton's second law of motion, force (F) = mass (m) times acceleration (a). We can do a little algebra and solve for the acceleration of the object in terms of the net external force and the mass of the object ( a = F / m).
How many newtons does it take to move 1kg?
The acceleration of gravity is 9.8 m/sec^2 so the effective force on a 1 kg object due to gravity is 9.8 Newtons.
How many newtons is a kg?
9.81 NKg and NewtonValuesKg to Newton1 kg = 9.81 NNewton to kg1N = 0.10197 kg
How do you calculate kg force?
Force FormulaThe formula for force states that force is equal to mass multiplied by acceleration. ... To solve this problem, just multiply the mass (2 kg) by the acceleration (2 m/s2) to get the final answer: 4 N of force was exerted on the box. ... Let's use the circle again.
What is the force of a ball?
The forces are the weight, drag, and lift. Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion.
How do you calculate the force of gravity?
To calculate the force of gravity of an object, use the formula: force of gravity = mg, where m is the mass of the object and g is the acceleration of the object due to gravity. Since g is always 9.8 m/s^2, just multiply the object's mass by 9.8 and you'll get its force of gravity!
When a ball falls to the floor what force is pulling on it?
Why does it fall to the ground? According to Newton's model of gravity, a force pulls the ball to the ground. Two lines of evidence support the claim that gravity is a force.
What is the net force acting on a 10 kg freely falling object?
Answer and Explanation: A 10 N freely falling object will have a net force of 10 N acting on it.
Is the net force of an object in free fall zero?
The net force is not zero. Nothing balances the gravity force mg on the object.
How is net force calculated?
Net force is the sum of all forces acting on an object. The net force can be calculated using Newton's second law, which states that F = ma, where: F is the net force. m is the mass of the object.
How many forces act on a freely falling object?
When the only force acting on an object is gravity, the object is said to be in free fall. The force of gravity causes the object to accelerate. Free fall is motion where the acceleration is caused by gravity. When something falls on Earth, there is fluid friction from the air around it.
Answer
Force = mass * acceleration, with units kg*m / second squared, or the more commonly the Newton, N. Assuming objects freely fall due to gravity at 9.8 m/second squared, and zero air resistance force opposing the freely falling object, 1 kg * 9.8 m/second squared = 9.8 N = force on the ball.
Answer
That force is called the "weight" of the ball. If it's anywhere on or near the Earth's surface, it's 9.8 Newton's (2.205 pounds). It makes no difference whether the ball is rising, falling, just laying there, rolling through air, or floating in chicken soup.
How much does a falling 1 kg object weigh?
The weight of the falling 1 kg object is still the same from its highest point to its lowest point. It is 9.8 newtons.
Why isn't an object falling in the Earth's gravitational field in free fall?
Interesting question: the correct answer is none, but only because you said “freely falling.” An object falling in the Earth’s gravitational field is not in free fall because there is no way of situating it in a reference frame in which it is not accelerating. An object in free fall has its own inertial reference frame in which it is by definition not accelerating, like astronauts on the space station. If your 1 kg weight is falling in the Earth’s atmosphere the force will be near 9.8 Newtons (depending on altitude) as others have said.
What is the gravitational force of the Earth?
It is what decides how much we weigh and how far a basketball will travel when thrown before it returns to the surface. The gravitational force on Earth is equal to the force the Earth exerts on you. At rest, on or near the surface of the Earth, the gravitational force equals your weight. On a different astronomical body like Venus or the Moon, the acceleration of gravity is different than on Earth, so if you were to stand on a scale, it would show you that you weigh a different amount than on Earth.
What is the acceleration due to gravity?
That means that the body is indeed acted upon by a force F=ma, where the acceleration a = g i.e. the acceleration due to gravity which near the Earth's surface is about 9.81m/s/s.
Why is weight measured in kilograms?
The reason why people refer to the weight of certain things on earth as being measured in kilograms is that, on earth, gravity is the same everywhere. Therefore, when given the mass of an object, one can easily find out the weight of the object, and if tw
What is free fall?
what is free fall -Whenever an object falls toward earth under the force of gravity one and no other force is present, the motion of the object is said to be “ free fall”
What is Newton's law of universal gravity?
what is gravitational force- Newton’s Law of Universal Gravitation is used to explain gravitational force? This law states that every massive particle in the universe attracts every other massive particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This general, physical law was derived from observations made by induction. Another way, more modern, way to state the law is: ‘every point mass attracts every single other point mass by a force pointing along the line intersecting both points. The force is proportional to the product of the two masses and inversely proportional to the square of the distance between the point masses’.
