Physics Section A : Speed and Acceleration

Part 1: Information

Acceleration

This refers to an increase in speed, or if the speed decreases, we talk about deceleration.

ACCELERATION   = 

Change in speed

Time taken to make this change

The S.I units for acceleration are m/s/s which can be written as m/s² or ms-2
 

SPEED-TIME graphs

These refer to the acceleration of an object and are very similar to distance-time graphs : so you to need look at the axes of the graphs very carefully.

Look at these following sites :
