What is the term used to describe the rate of change of velocity?

• Speed

• Distance

• Acceleration

• Time

Velocity is a property of motion. How is it different from speed?

• Velocity includes direction, speed does not.

• Velocity is always greater than speed.

• Velocity is measured in kilograms.

• Velocity is a scalar quantity.
