Front

What is velocity?

Back

Velocity is speed in a given direction, making it a vector quantity.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

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).

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to a reference point.
