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 energy.

Front

At which point is potential energy greatest in a roller coaster?

Back

Potential energy is greatest at the highest point of the roller coaster.

Front

Where is maximum kinetic energy on a roller coaster?

Back

Maximum kinetic energy is at the bottom of a big hill.

Front

What type of energy does a moving skateboard have?

Back

A moving skateboard has kinetic energy.

Front

Which example best illustrates kinetic energy?

Back

A tennis ball rolling across the court is a clear example of kinetic energy.

Front

When is kinetic energy highest in a pendulum swing?

Back

Kinetic energy is highest at the lowest point of the swing.

Front

What factors affect kinetic energy?

Back

Kinetic energy is affected by the mass of the object and the square of its velocity.

Front

What is the formula for 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 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.
