Potential and Kinetic 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 be converted into kinetic energy.

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 is the formula for Kinetic Energy?

Back

The formula for Kinetic Energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for Potential Energy?

Back

The formula for Potential Energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is Mechanical Energy?

Back

Mechanical Energy is the sum of potential energy and kinetic energy in an object that is used to do work.

What happens to energy during a roller coaster ride?

Back

As the roller coaster climbs, potential energy increases; as it descends, potential energy converts to kinetic energy.

Front

What is an example of converting chemical energy to thermal energy?

Back

Burning charcoal in a grill converts chemical energy stored in the charcoal to thermal energy used for cooking.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has elastic potential energy due to its position.

Front

What is an example of kinetic energy in sports?

Back

A moving soccer ball has kinetic energy due to its motion.

Front

How does height affect potential energy?

Back

The higher an object is positioned, the greater its potential energy due to increased height (h) in the formula PE = mgh.
