Question

what is acceleration define.​

Answer 1

Answer:

In physics, acceleration is the rate of change of velocity of an object with respect to time. An object's acceleration is the net result of all forces acting on the object, as described by Newton's Second Law.

Answer 2

Answer:

change in velocity in particular time.

Explanation:

a=v-u/t

acceleration is a vector quantity i.e it has both mag and direction.

for ex if u are travelling in a bike and u don't increase or decrease the accelerator then the acceleration is zero.

acceleration exists only if there is a change in velocity.
