Kinetic and Potential energy

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

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 an example of potential energy?

Back

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

Front

What is an example of kinetic energy?

Back

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

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 type of energy does a roller coaster have at the top of a hill?

Back

At the top of a hill, a roller coaster has maximum potential energy.

Front

What type of energy does a roller coaster have at the bottom of a hill?

Back

At the bottom of a hill, a roller coaster has maximum kinetic energy.

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.
