Question

Deceleration is negative acceleration explaination

Answer 1

acceleration is the rate of change of velocity so when the direction plus the speed of the moving object changes with the time it is known as acceleration but when it decreases with the time then it is known as negative acceleration or deceleration

Answer 2

Answer:

If an object having initial velocity u attains a velocity v after a time t, then acceleration a = (v - u/t. When velocity of an object increases with time, then acceleration is positive. If velocity of an object decreases with time, then acceleration is negative. Negative acceleration is also called retardation. Acceleration can be uniform or non-uniform. A freely falling body has a uniform acceleration of 9.8 m/s2 When a car moves with variable velocity, then the acceleration of car is non-uniform. For an object moving with uniform velocity, the acceleration is zero.
