Potential & 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 has the potential to do work when released.

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

At which point of a roller coaster is potential energy the greatest?

Back

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

Front

At which point of a roller coaster is kinetic energy the greatest?

Back

Kinetic energy is greatest at the lowest point of the roller coaster.

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 is the relationship between speed and kinetic energy?

Back

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

Front

What type of energy is stored in gasoline?

Back

Gasoline contains potential energy.

Front

What type of energy is present in a stretched rubber band?

Back

A stretched rubber band has potential energy.

Front

How is potential energy calculated?

Back

Potential energy (PE) is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How is kinetic energy calculated?

Back

Kinetic energy (KE) is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.
