Question

What is the relationship between acceleration and speed?

Answer 1

The relationship between acceleration and velocity is that they are both related to speed. Also, they are each other. The only difference is that acceleration is a change in speed/direction. Velocity is just a speed.

Answer 2

Answer:

The relationship between acceleration and speed:

Consider a body having initial velocity "u". Let the body be acted upon by some force for "t" seconds, such that its final velocity is "v".

Therefore, change in velocity in time = v - u

Therefore, change in velocity in time 1 second, acceleration = v - u / t

Change in velocity in one second is called acceleration.

Therefore, a = v - u / t

=> v - u = at

=> v = u + at
