# Rate of change of velocity is called ____?

The rate of change of velocity is called acceleration and the kind of motion is known as accelerated motion.

## Acceleration

• Acceleration is defined as the rate of change of velocity with respect to time.
• Acceleration is a vector quantity, so it includes both magnitude and direction.
• Velocity is the rate at which displacement changes with time.
• Instantaneous acceleration is defined as the ratio of change in velocity during a given time interval such that the time interval goes to zero.
