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 can be gravitational, elastic, or chemical.

Front

At which point is potential energy greatest in a gravitational field?

Back

Potential energy is greatest at the highest point in a gravitational field.

Front

What type of energy does a rock at the edge of a cliff have?

Back

The rock has potential energy because of its height above the ground.

Front

What is an example of potential energy?

Back

The pulled back string on an archer's bow is an example of potential energy.

Front

When you stretch a rubber band, what type of energy are you storing?

Back

You are storing potential energy when you stretch a rubber band.

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 the formula for calculating 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 gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass; if the mass of an object doubles, its kinetic energy also doubles if the velocity remains constant.
