Front

What is needed to change or start motion?

Back

Force

Front

What measures the speed of an object plus its direction?

Back

Velocity

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is a reference point?

Back

A reference point is a stationary object used to determine the position of another object.

Front

What is acceleration?

Back
