Unit 2 Vocab - Force and Motion

Front

Inertia in motion = mass x velocity

Back

momentum

Front

Change in an object's position or direction

Back

Motion

Front

How far an object has travelled?

Back

Distance

Front

How quickly an object moves in m/s

Back

speed

Front

Speed in a direction (m/s north)

Back

velocity

Front

Increase/decrease in speed, measured in m/s²

Back

acceleration

Front

An object in motion stays in motion; an object at rest stays at rest unless acted on by an unbalanced force.

Back

Newton's 1st Law of Inertia

Front

Acceleration depends on mass and force: F = m × a.

Back

Newton's 2nd Law

Front

For every action, there is an equal and opposite reaction.

Back

Newton's 3rd Law

Front

Forces on an object that combine to form a net force of zero.

Back

Balanced forces
