Question

What is acceleration?

Answer 1

Acceleration : The rate of change of velocity of an object with respect to time is called acceleration.

Or

The change in velocity per unit time is called acceleration.

$acceleration = \frac{change \: \: in \: \: velocity}{time \: \: taken}$

But the change in velocity is the difference between final velocity and initial velocity.

so,
Change in velocity = final velocity - initial velocity

Therefore,

$acceleration = \frac{final \: \: velocity - initial \: \: velocity}{time \: \: taken}$

Answer 2

Acceleration :

• The change in velocity of a body per unit time is called acceleration or the rate of change of velocity is called acceleration.
• Acceleration = change in velocity/total time
• The SI unit of acceleration is m/s^2.
• The other units are cm/s^2 and km/h^2
• Acceleration depends on velocity and time interval
