Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

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

Front

What is Potential Energy?

Back

Potential energy is stored energy that has the potential to do work. It is energy based on an object's position or state.

Front

What type of energy is associated with food?

Back

Chemical potential energy.

Front

At what point does a diver have the greatest kinetic energy during a dive?

Back

At the lowest point of the dive, just before entering the water.

Front

Which car has greater kinetic energy: Car A traveling at 20 m/s or Car B traveling at 30 m/s?

Back

Car B, because kinetic energy increases with the square of the velocity.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses because of its position in a gravitational field, typically related to its height.

Front

What is an example of elastic potential energy?

Back

A compressed spring or a stretched rubber band.

Front

How does height affect potential energy?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.

Front

What happens to kinetic energy as an object slows down?

Back

As an object slows down, its kinetic energy decreases.
