Acceleration - The change in velocity.
It is a vector quantity, and therefore can be positive or negative and therefore refers to a change in direction as well as a change in speed.
To work out the acceleration of something you need to know:
- The velocity it started at (in metres per second) - this is written as u
- The velocity it ends up at (in metres per second) - this is written as v
- The time it took to change velocity (in seconds) - this is written as t.
The equation is:
Acceleration (m/s^2) = change…
