Define acceleration?????? |
| Answer» ATION:The rate of change of velocity of an object with respect to time is KNOWN as ACCELERATION.i.e.Acceleration = Velocity is measured in m/sTime measured in s (SEC)So,S.I. unit of acceleration = m/s²Types of acceleration :» Positive acceleration» Negative acceleration» ZERO accelerationDimension :Dimension for velocity is LT-¹Dimension for time is TSo,Dimension of acceleration is LT-²It is a vector quantity. As it has both magnitude and direction. ____________________________ | |
