What are three changes in motion show that an object is accelerating

What shows that an object is accelerating

1. If the velocity is increasing.

From equation of motion

a = ∆v / t

So, if the velocity increases with time, the acceleration increases. But if it decreases with time, it decelerating.

2. Also, from newton second law,

F = ma

a = F / m

Where a = acceleration

F is force applied

m is the mass

So, if the force is increase and the mass is reduced, then the acceleration is increase.

3. Also, in. Circular motion,

a = w²r

Where

a is linear acceleration

w is angular speed

r is the radius.

So, when the angular speed is increased, then the linear acceleration is increased.
