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.
