Kinetic and Potential Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It is often associated with gravitational energy when an object is elevated.

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

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.

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 type of energy does a stretched rubber band have?

Back

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

Front

At what point in a pendulum's swing is potential energy the greatest?

Back

Potential energy is greatest at the highest points of the pendulum's swing.

Front

What type of energy is greatest at the bottom of a hill?

Back

Kinetic energy is greatest at the bottom of a hill when an object is moving the fastest.

Front

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

Back

In a roller coaster, potential energy is converted to kinetic energy as the coaster descends from a height.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).
