An Introduction to Acceleration SPH4C

3
Acceleration Acceleration is defined as the change in the velocity of an object per interval of time, or:

Acceleration

6
Acceleration v 2 = final velocity and v 1 = initial velocity

7
Acceleration Acceleration will have units of m/s/s or m/s 2. (Notice also that acceleration is a vector.)
