Kinetic and Potential Energy Practice

Front

What type of energy is highest when a pendulum is at its lowest point?

Back

Kinetic energy is highest at the lowest point of the pendulum's swing.

Front

What type of energy does a roller coaster have at the top of a hill?

Back

High potential energy.

Front

What is stored energy called?

Back

Potential energy.

Front

What type of energy does a balloon filled with air possess?

Back

Potential energy.

Front

What is the energy due to motion called?

Back

Kinetic energy.

Front

What happens to potential energy as an object falls?

Back

It decreases as kinetic energy increases.

Front

What is the formula for kinetic energy?

Back

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

Front

What is the formula for potential energy?

Back

Potential Energy = mgh (where m is mass, g is acceleration due to gravity, and h is height).

Front

How does height affect potential energy?

Back

Potential energy increases with height.

Front

What happens to the total mechanical energy in a closed system?

Back

It remains constant (conservation of energy).
