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 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 its velocity.

Front

How is potential energy calculated?

Back

Potential energy (PE) can be 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) can be calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, assuming no energy is lost to air resistance.

Where is potential energy highest on a roller coaster?

Back

Potential energy is highest at the top of the highest hill on a roller coaster.

Front

Where is kinetic energy highest on a roller coaster?

Back

Kinetic energy is highest at the bottom of the hills on a roller coaster.

Front

What is an example of kinetic energy in everyday life?

Back

An example of kinetic energy is a moving car or a person running.

What is an example of potential energy in everyday life?

Back

An example of potential energy is a stretched rubber band or a book on a shelf.

Front

What is the relationship between potential and kinetic energy?

Back

Potential and kinetic energy are interconvertible; as potential energy decreases, kinetic energy increases and vice versa.
