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

At which point in a pendulum's swing is kinetic energy highest?

Back

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

Front

Where is gravitational potential energy highest in a room?

Back

Gravitational potential energy is highest at the highest point in the room, such as the ceiling.

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

When you stretch a rubber band, what type of energy are you storing?

Back

You are storing potential energy when you stretch a rubber band.

Front

What is the formula for calculating 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 gravitational 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.

Front

How does height affect potential energy?

Back

The higher an object is, the greater its potential energy due to the increased height in the gravitational field.

Front

What is an example of elastic potential energy?

Back

An example of elastic potential energy is a compressed spring or a stretched rubber band.
