Potential Energy and Kinetic Energy Practice

Front

What is energy?

Back

Energy is the ability to do work.

Front

Where would a person have to be located to have the maximum gravitational potential energy?

Back

A person would have maximum gravitational potential energy up on the roof.

Front

Gravitational potential energy depends on which two factors?

Back

Gravitational potential energy depends on height and mass.

Front

What does the Law of Conservation of Energy state?

Back

The Law of Conservation of Energy states that the total amount of energy is conserved before and after a reaction.

Front

While a boulder is on the top of a hill, what type of energy does it have?

Back

While on the top of a hill, a boulder has potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with the mass of the object; more mass means more kinetic energy.

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases as height increases.
