Question

give 2 example of negetive acceleration​

Answer 1

Answer:

1) When a moving body slows down due to any reason, the speed decreases and the acceleration is negative. 2) A cyclist is cycling and stops after 60 seconds. While stopping, the speed deceases and therefore, it leads to retardation and acceleration is negative

Answer 2

Some common examples are :

→A car is moving with high velocity (say v1 = 100km/hr toward North) suddenly it's driver notices a dog crossing the road, applies the brake and reduces the velocity of car to zero(v2 = 0) in 10 seconds (t2 - t1 = 10). So v2 -v1 is negative, implies negative acceleration.
