✍ Acceleration

  • Acceleration is the  rate of change of velocity with time.
  • It  is defined as change of velocity of body per unit time.
  • SI unit of acceleration is m/s²
  • It is Vector Quantity.
  • Acceleration = Change in velocity / time

       = Final velocity - Initial velocity / time

       = v - u / t

✍ Types of Acceleration

1. Uniform Acceleration

If the velocity changes in equal amounts in equal time of intervals and the object travels in a straight line than the uniform acceleration take place.

2. Non-uniform Acceleration

If the velocity changes in an equal amount in unequal intervals of time and object travels in straight line then non uniform acceleration take place.

♣ Zero Acceleration -  

  • If the change in velocity is zero that is either object is at rest or moving with uniform velocity than zero acceleration will take place.

♣ Positive Acceleration -  

  • When velocity of a body increases then positive acceleration take place.
  • i.e v > u

♣ Negative Acceleration -  

  • When velocity of a body decreases the negative acceleration take place.
  • It is in the opposite direction of velocity.
  • i.e v < u
