How is the gravitational force between two objects related to their mass?

Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.

How does the kinetic energy of an object change if mass is doubled and its velocity is halved?

3..if mass doubled and velocity reduced to half kinetic energy will be half the initial value..

How do you find the force of N?

What is the formula for force? The force formula is defined by Newton’s second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.

What is the accepted value of acceleration due to gravity?

9.8 m/s/s.
The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.

What is the gravitational force between two objects Class 10?

This universal attractive force is called “Gravitational”. Newton’s law:- Force of attraction between any two material particles is directly proportional to the product of masses of the particles and inversely proportional to the square of the distance between them. It acts along the line joining the particles.

Which happen to kinetic energy if mass is double?

Kinetic energy is the energy of mass in motion. When we double the mass, we double the energy; however, when we double the velocity, energy increases by a factor of four.

What is the numerical formula for force Class 9?

Newton’s Second Law For a constant mass, force equals the mass times acceleration, i.e. F = m x a.

How was acceleration due to gravity discovered?

In studying how objects fall toward Earth, Galileo discovered that the motion is one of constant acceleration. He demonstrated that the distance a falling body travels from rest in this way varies as the square of the time.

What is the value of Universal Gravitation Constant?

Ans: The value of universal gravitation constant is 6.672 x 10 -11 N m 2 /kg 2. The distance of a planet from the earth is 2.5 x 107 km and the gravitational force between them is 3.82 x 1018 N. Mass of the planet and earth are equal, each being 5.98 x 1024 kg.

How to find the gravitational force of attraction between two masses?

Calculate the gravitational force of attraction between the two masses. Also, find the initial acceleration of two masses assuming no other forces act on them. Given: Mass of first body = m 1 = 5 kg, mass of second body = m 2 = 6 x 10 24 kg, Distance between masses = r = 6.4 x 10 6 m, G = 6.67 x 10 -11 N m 2 /kg 2 .

What is the force of attraction between a 40 kg and 15 kg?

A sphere of mass 40 kg is attracted by another spherical mass of 15 kg by a force of 9.8 x 10-7 N when the distance between their centres is 0.2 m. Find G. Given: Mass of first body = m 1 = 40 kg, mass of second body = m 2 = 15 kg, force between them = F = 9.8 x 10 -7 N, Distance between the masses = r = 0.2 m.

How do you calculate the force of gravity on the Moon?

The mass of the earth is 6 × 1024 kg and that of the moon is 7.4 × 1022 kg. If the distance between the earth and the moon is 3.84×105 km, calculate the force exerted by the earth on the moon. (Take G = 6.7 × 10–11 N m²/kg²) Q 3.
