Kinetic and Potential Energy Flashcard

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 Potential Energy?

Back

Potential energy is the stored energy of an object due to its position or state. It can be gravitational, elastic, or chemical.

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 kinetic energy in everyday life?

Back

A moving car, a flowing river, or a flying baseball are all examples of kinetic energy.

Front

What is an example of potential energy?

Back

A book on a shelf, a drawn bow, or water stored in a dam are examples of potential energy.

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.

Front

How is potential energy calculated?

Back

Gravitational 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.

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.

What is the relationship between kinetic and potential energy in a pendulum?

Back

In a pendulum, kinetic energy is highest at the lowest point, while potential energy is highest at the highest points.
