Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a rock at the top of a hill has potential energy because of its height.

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 potential energy change when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, as it converts potential energy into kinetic energy.

Front

What happens to energy at the top of a roller coaster?

Back

At the top of a roller coaster, potential energy is at its maximum, and as the coaster descends, this potential energy is converted into 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 potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy due to its position and tension.

Front

What type of energy is associated with moving water?

Back

Moving water has kinetic energy because it is in motion.

Front

What is the relationship between potential and kinetic energy in a pendulum?

Back

In a pendulum, potential energy is highest at the highest point, and kinetic energy is highest at the lowest point.

Front

What is an example of potential energy in everyday life?

Back

An example of potential energy is a book on a shelf, which has energy due to its height.
