What is acceleration ? ?

Question

What is acceleration ? ?

Answer 1

V=velocity vector (it has magnitude called speed and direction)

a = acceleration vector = dV/dt = rate of change of (slope of, if you graph V versus t) the velocity vector.

You can thus accelerate in TWO ways...

1) Change speed

2) Change direction

So in your car, the accelerator/brake is one acceleration control, the steering wheel is the other.

Answer 2

Acceleration is defined as the rate of change of velocity

Acceleration= change in velocity/ time taken

Answer 3

acceleration is how long it takes to reach a desired speed. velocity is just the direction of speed  

Answer 4

The rate of change of velocity.

Answer 5

An acceleration is a change of velocity.
