Energy Flashcard Review

Front

What is kinetic energy?

Back

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

Front

What two factors does kinetic energy depend on?

Back

Kinetic energy depends on mass and speed of the object.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or height. It is the energy an object has before it starts moving.

Front

Where is potential energy highest in a swing?

Back

Potential energy is highest at the highest point in the swing.

Front

Where is kinetic energy highest in a swing?

Back

Kinetic energy is highest at the lowest point in the swing.

Front

What is gravitational energy?

Back

Gravitational energy is the potential energy held by an object because of its height above the ground.

Front

What type of energy does a weight have before a rope is cut?

Back

Before the rope is cut, the weight has potential energy.

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 is KE = 1/2 mv², where m is mass and v is speed.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is energy of motion, while potential energy is stored energy based on position.
