What is Potential Energy (PE)?

Back

Potential Energy (PE) is the energy stored in an object due to its position or configuration. It is the energy an object has because of its height above the ground.

Front

What is Kinetic Energy (KE)?

Back

Kinetic Energy (KE) is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

Where is potential energy the greatest in a gravitational field?

Back

Potential energy is greatest at the highest point in a gravitational field, where the object has the most height.

Front

Where is kinetic energy the greatest in a gravitational field?

Back

Kinetic energy is greatest just before an object hits the ground, where it has the highest speed.

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 happens to kinetic energy as an object rises?

Back

As an object rises, its kinetic energy decreases while its potential energy increases.

Front

What is the relationship between potential energy and height?

Back

Potential energy is directly proportional to height; as height increases, potential 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

What is the formula for calculating potential energy?

Back

The formula for potential energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
