What is the potential energy of a stone of mass 10kg that is lifted to a height of 8m given G 10n kg?

Hence, the potential energy of a stone is 800 J.

When an object of 5 kg is lifted through 3 m by application of force the work done is?

The correct answer is 25 J.

What is the work done against gravitational force if an object of 20 kg mass is raised to a height of 2m?

W = mgh = 20 × 9.8 × 2 = 392 J.

How much velocity will an object of mass 10kg transfer to the floor if its falls from a height of 5m G 10 m s2 *?

AnsweR : Momentum is 100 kgm/s.

What energy is possessed by an object that is lifted at a certain height?

gravitational potential energy
To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.

What is the energy possessed by an object of mass 10kg?

Potential Energy of 588 Joule is possessed by object which is of mass 10 kg.

What is the work done in lifting a 5 kg body through a height of 10m?

The formula for potential energy due to gravity is PE = mgh. As the object gets closer to the ground, its potential energy decreases while its kinetic energy increases. In this case, a body of mass 5 kg kept at a height of 10 m. So the potential energy is given as 5 * 10 *10 = 500 J.

What is work done in lifting a body of mass 5 kg vertically through 9m?

Answer is correct. If you take g as 9.8 m/s^2 then answer will by 392 joule.

How much work will be done to lift 20kg weight on a height of 20m?

The work done is the product of force and displacement. Force is the product of mass and acceleration which in this case is acceleration due to gravity. Thus the work done to lift the load is 196J.

What is the work done in lifting a mass of 10 kg through a height of 5 Metres from the ground?

What is the work done? ∴ Work done, W =Fs =98×5J=490J .

How much momentum will an object of mass 10kg transfer to the floor if it falls from height of 80 cm?

Momentum= 10×4= 40kg m/s.

How much momentum will a dumbbell of mass 10kg transfer to the floor if it falls from a height of 10cm and rebounds with the same speed?

Hence, the momentum with which the dummbell hits the floor is 40 kg m/s.

What is the GPE of an object with mass 50 kg?

An object with mass 50 kg and height 20 m has GPE of = 50 x 9.8 x 20 = 9800 Joules In general, the gravitational potential energy (GPE) arises from the law of gravity and is equal to the work done against gravity to bring a mass to a given point in space.

What is the value of gravitational acceleration with mass and height?

The gravitational acceleration is assumed to be a constant whose values is equal to 9.8 m/s 2. Use this online gpe calculator to determine the gravitational potential energy with the known values of mass and height. Gravitational Potential Energy (GPE) is defined as the energy possesed by an object due to its position in the gravitational field.

What is the work done by gravity on a 15 kg box?

A 15 kg box falls at angle 25 ∘ from a height of 10 m. Determine the work done by gravity. Therefore, the work done by gravity is 1332 J.

How do you calculate kinetic energy from mass and velocity?

Kinetic Energy. In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2.
