Unit 3 PS: Energy and Waves

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It can be calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is the height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It can be calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What does the Law of Conservation of Energy state?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another or transferred between objects.

Front

What are the two main categories of energy?

Back

The two main categories of energy are potential energy and kinetic energy.

Front

What is chemical energy?

Back

Chemical energy is a form of potential energy stored in the bonds of chemical compounds, like atoms and molecules.

Front

How does energy transformation occur in an isolated system?

Back

In an isolated system, as energy transformations occur, the total energy of the system remains constant.

Front

What is the formula for calculating potential energy?

Back

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

Front

What is the formula for calculating kinetic energy?

Back

The formula for calculating kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.

Front

Can energy be created or destroyed?

Back

No, according to the Law of Conservation of Energy, energy cannot be created or destroyed.

Front

What is an example of potential energy?

Back

An example of potential energy is a rock held at a height above the ground, which has gravitational potential energy.
