Physical Science Final Review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is highest when the object is at its highest point in a gravitational field.

At which point does a roller coaster car have the greatest potential energy?

Back

The roller coaster car has the greatest potential energy at the highest point of the track.

Front

What is the relationship between pressure and volume in gases?

Back

According to Boyle's Law, at constant temperature, the pressure of a gas is inversely proportional to its volume.

Front

Which state of matter is most easily compressed?

Back

Gases are the most easily compressed state of matter due to the large spaces between particles.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What causes the backward push felt by a firefighter using a hose?

Back

The backward push is due to Newton's Third Law: for every action, there is an equal and opposite reaction.

Front

What is an ionic bond?

Back

An ionic bond is a chemical bond formed through the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the formation of ions, while covalent bonds involve the sharing of electrons.

Front

What is the definition of a solid?

Back

A solid is a state of matter that has a definite shape and volume.
