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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.
