Acceleration: The state of change of velocity of a body with time is known as its acceleration.
If the velocity of a body increases with time, then its acceleration is positive. On the other hand, if the velocity of a body decreases with time, then its acceleration is negative. Negative acceleration is also called retardation or deceleration. Acceleration is a vector quantity.
Units of acceleration. The units of acceleration are: Continue reading “Acceleration, average Acceleration, uniform Acceleration, variable Acceleration, instantaneous Acceleration”
