Energy Flashcard Review PS

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 is energy converted from potential to kinetic?

Back

Energy is converted from potential to kinetic when an object moves from a higher position to a lower position, such as a ball rolling down a hill.

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

What happens to energy in a closed system?

Back

In a closed system, energy is conserved; it can change forms but cannot be created or destroyed.

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 the formula for potential energy?

Back

The formula for gravitational potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What type of energy does a drawn bow possess?

Back

A drawn bow possesses elastic potential energy.

Front

What type of energy does a compressed spring have?

Back

A compressed spring has potential energy.

Front

What is nuclear potential energy?

Back

Nuclear potential energy is the energy stored in the nucleus of an atom, which is the most concentrated form of energy.
