Potential and Kinetic Energy Flashcard

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a stretched rubber band has potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

How does mass affect kinetic energy?

Back

Increasing an object's mass will increase its kinetic energy, as kinetic energy is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

At which point is potential energy greatest in a roller coaster?

Back

Potential energy is greatest at the highest point of the roller coaster.

Front

What type of energy does a moving car have?

Back

A moving car has kinetic energy.

Front

What type of energy does a book on a shelf have?

Back

A book on a shelf has potential energy due to its height above the ground.

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 calculating kinetic energy?

Back

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

Front

Can energy change forms?

Back

Yes, energy can change from potential to kinetic and vice versa, such as when a ball is dropped.

Front

What is an example of potential energy in everyday life?

Back

An example of potential energy is a stretched rubber band or a water reservoir at a height.
