Potential and Kinetic Energy

Front

What is the definition of work in physics?

Back

Work is the exertion of force over a distance, resulting in energy transfer.

Front

What is Kinetic Energy (KE)?

Back

Kinetic Energy is the energy an object possesses due to its motion.

Front

What is Potential Energy (PE)?

Back

Potential Energy is the energy stored in an object due to its position or state.

Front

How does Kinetic Energy change with speed?

Back

Kinetic Energy increases with the square of the speed of the object.

Front

What is Elastic Potential Energy?

Back

Elastic Potential Energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

When is Elastic Potential Energy at its maximum?

Back

Elastic Potential Energy is at its maximum when the elastic material is stretched or compressed to its limit.

Front

What unit is used to measure energy?

Back

The unit used to measure energy is the Joule (J).

Front

What happens to Potential Energy when an object is lifted higher?

Back

Potential Energy increases as the height of the object increases.

Front

What is the relationship between Kinetic Energy and mass?

Back

Kinetic Energy is directly proportional to the mass of the object; as mass increases, Kinetic Energy increases.

Front

What is the formula for Kinetic Energy?

Back

The formula for Kinetic Energy is KE = 1/2 mv², where m is mass and v is velocity.
