Potential and Kinetic Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. It depends on the mass of the object and its speed.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

What are the two factors that affect kinetic energy?

Back

Mass and speed.

Front

Give an example of an object with kinetic energy.

Back

A tennis ball rolling across the court.

Front

What happens to energy at the top of a roller coaster?

Back

Kinetic energy is transformed into potential energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses because of its height above the ground.

Front

How does a ball rolling down a ramp demonstrate energy transformation?

Back

It shows the transformation from potential energy (at the top) to kinetic energy (as it rolls down).

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with an increase in mass if speed remains constant.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by four times.

Front

What is an example of potential energy?

Back

A car parked on a steep hill has potential energy due to its height.
