Back to: 1. Straight Line Motion: Velocity and Acceleration

………………………………………………..

How do we calculate acceleration?

………………………………………………..

## Read the following derivations. You must remember the following formulae:

If an object travels at constant acceleration a, from an initial velocity u, to a final velocity v, taking a time t, then

The average velocity of the object will be

Since average velocity= displacement/time, this follows that the displacement s is

In the video below, I solve a sample problem to show you how these formulae can be used.
