Answer:
The rate of change of velocity with respect to time.
Acceleration is a vector quantity as it has both magnitude and direction. It is also the second derivative of position with respect to time or it is the first derivative of velocity with respect to time.
Acceleration formula is given as:
acceleration=(finalvelocity)−(initialvelocity)time acceleration=changeinvelocitytime a=vf−vit
a=Δvt
Where,
a is the acceleration in m.s-2
vf is the final velocity in m.s-1
vi is the initial velocity in m.s-1
t is the time interval in s
Δv is the small change in the velocity in m.s-1
The SI unit of acceleration is given as:
SI unit m/s2
