Kinetic and Potential Energy

A body with a mass of 10kg is raised at a height of 5m from the ground. Calculate the gravitational potential energy of the body.

• 460 J

• 470 J

• 480 J

• 490 J

If the mass is doubled, what happens to the gravitational potential energy?

• Gravitational potential energy will turn into half.

• Gravitational potential energy will be the same.

• Gravitational potential energy will also double.

• Gravitational potential energy will become quadruple.

A little boy climbed up a 10 meter high building while the monkey climbed up a 20 meter high tree. If the little boy and the monkey have the same mass, who will exhibit a greater  potential energy?

• Little boy exhibits greater potential energy.

• Monkey exhibits greater potential energy.

• Both exhibit greater potential energy.

• Neither of them exhibits greater potential energy.

An object with a mass of 5kg is moving at a velocity of 2m/s. What is the kinetic energy of the object?

• 5 J

• 10 J

• 15 J

• 20 J

If the velocity of the body is doubled, what happens to the kinetic energy of the body?

• Kinetic energy will turn into half.

• Kinetic energy will be the same.

• Kinetic energy will also double.

• Kinetic energy will become quadruple.
