Elastic Potential Energy Review

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

Which object has elastic potential energy?

Back

A stretched bow.

Front

What unit is used for the potential energy of a spring?

Back

Joule.

Front

What is the ability to move, change matter, or to do work called?

Back

Energy.

Front

What is the energy of moving matter called?

Back

Kinetic energy.

Front

What happens to elastic potential energy when a spring is compressed?

Back

It increases as the spring is compressed.

Front

What is the relationship between the stiffness of a spring and its potential energy?

Back

A stiffer spring stores more potential energy per meter of stretch.

Front

What is the formula for calculating elastic potential energy?

Back

EPE = 1/2 k x^2, where k is the spring constant and x is the displacement.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is the energy of motion.

Front

Can elastic potential energy be converted to kinetic energy?

Back

Yes, when an elastic object returns to its original shape, the stored potential energy is converted to kinetic energy.
