12B Gravity Vocab Practice

The force of attraction between any two masses.

• terminal velocity

• gravity

• net force

• centripetal force

This is the last speed a falling object reaches when the force of air resistance matches the force of gravity causing a falling object to stay at a constant speed.

• actual velocity

• responding velocity

• terminal velocity

• relative velocity

This is the man that is considered to be the "Father of Modern Physics"

• Galileo

• Bill Nye

• Isaac Newton

• Copernicus

The tendency of an object resist change

• inertia

• friction

• laziness

• constant
