Kinetic and Potential Energy Review

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a boulder resting on a cliff has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. For example, a soccer ball rolling on the ground has kinetic energy.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy can neither be created nor destroyed; it can only be transformed from one form to another.

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object to another. For example, when a ball is kicked, energy is transferred from the foot to the ball.

Front

What is an example of an object with only potential energy?

Back

A boulder resting on top of a cliff is an example of an object with only potential energy.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car is an example of kinetic energy in everyday life.

Front

How does height affect potential energy?

Back

The higher an object is positioned, the more potential energy it has due to the gravitational force acting on it.

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 formula for kinetic energy?

Back

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

Front

What is the formula for potential energy?

Back

The formula for potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
