Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What two factors affect an object's kinetic energy?

Back

Mass and speed.

Front

What is the formula for calculating kinetic energy?

Back

Front

Does increasing an object's mass increase its kinetic energy?

Back

Yes, increasing mass increases kinetic energy.

Front

Does increasing an object's speed increase its kinetic energy?

Back

Yes, increasing speed increases kinetic energy.

Front

What happens to kinetic energy if the speed is doubled?

Back

If speed is doubled, kinetic energy increases by a factor of four.

Front

What is the unit of kinetic energy?

Back

The unit of kinetic energy is Joules (J).

Front

If an object has a mass of 2 kg and is moving at a speed of 3 m/s, what is its kinetic energy?

Back

Front

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy is proportional to the square of the velocity.

Front

Can an object have kinetic energy if it is not moving?

Back

No, an object must be in motion to have kinetic energy.
