6.8A 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 the speed at which it is moving.

Front

How does height affect gravitational potential energy?

Back

Gravitational potential energy increases with height. The higher an object is, the more potential energy it has.

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 happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

At what point does a pendulum have maximum potential energy?

Back

A pendulum has maximum potential energy at its highest point in the swing.

Front

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

Back

In a roller coaster, potential energy is highest at the top of a hill, and kinetic energy is highest at the bottom.

Front

What is an example of an object with high potential energy?

Back

A book placed on a high shelf has high potential energy due to its elevated position.

Front

What is an example of an object with high kinetic energy?

Back

A moving car has high kinetic energy due to its mass and speed.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass; if two objects are moving at the same speed, the heavier object has more kinetic energy.
