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 unit is commonly used to measure speed?

Back

Front

What does acceleration measure?

Back

The rate of change of velocity over time.
