Kinetic and Potential Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical energy.

Front

How does speed affect kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

Where is kinetic energy the least for a moving object?

Back

Kinetic energy is least when the object is at rest or moving at the slowest speed.

Front

At what point does a falling object have the greatest kinetic energy?

Back

A falling object has the greatest kinetic energy just before it hits 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

Is it true that increasing an object's speed increases its kinetic energy?

Back

True, increasing an object's speed increases its kinetic energy.

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

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has elastic potential energy.
