Potential and Kinetic Energy Review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy an object has when it is at rest and has the potential to move.

Front

What is kinetic energy?

Back

Kinetic energy 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

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is the mass of the object and v is its velocity.

Front

What is the unit of measurement for potential energy?

Back

The unit of measurement for potential energy is Joule.

Front

How does height affect potential energy?

Back

The higher an object is positioned, the greater its potential energy. This is because potential energy is directly related to the height of the object above the ground.

Front

What happens to kinetic energy as an object slows down?

Back

As an object slows down, its kinetic energy decreases because kinetic energy is dependent on the speed of the object.

Front

At what point is potential energy greatest in a roller coaster?

Back

Potential energy is greatest at the highest point of the roller coaster.

Front

At what point is kinetic energy greatest in a roller coaster?

Back

Kinetic energy is greatest at the lowest point of the roller coaster, where the speed is highest.

Front

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

Back

In a closed system, potential energy can be converted into kinetic energy and vice versa, but the total energy remains constant.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
