Question

On which of the following factors does the kinetic energy of a body depend?

• A. Mass of the body
• B. Height of the body above Earth’s surface
• C. Speed of the body
• D. Shape of the body

Answer 1

Answer: (A), (C)

The correct options are
A

Mass of the body

C

Speed of the body

Kinetic energy is the energy obtained due to motion of a body. It depends on mass and speed of the body. For a given speed, more the mass of the body, more will be its kinetic energy. Similarly, for a given mass, more the speed, more will be the kinetic energy. Kinetic energy doesn't depend on height of the body above Earth's surface and its shape.
