Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is the unit of measurement for acceleration?

Back

Meters per second squared (m/s²)

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).
