Potential and Kinetic Energy

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the definition of potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often associated with gravitational potential energy, calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

At which point on a roller coaster is potential energy the highest?

Back

Potential energy is highest at the highest point of the roller coaster, typically at the top of a hill.

Front

At which point on a roller coaster is kinetic energy the highest?

Back

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

Front

What happens to kinetic energy as an object rises in height?

Back

As an object rises in height, its kinetic energy decreases while its potential energy increases, assuming no energy is lost to friction.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car, a flowing river, or a person running are all examples of kinetic energy.

Front

What is an example of potential energy in everyday life?

Back

A stretched rubber band, a book on a shelf, or water stored in a dam are all examples of potential energy.

Front

How does mass affect kinetic energy?

Back

Kinetic energy is directly proportional to mass; as mass increases, kinetic energy increases if velocity remains constant.

Front

How does height affect potential energy?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has due to the gravitational force acting on it.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
