Acceleration Change in Velocity ms Time s 4 ms 2 s 2 ms 2. Average acceleration is defined as the change in velocity divided by the time it took for the velocity change to take place. You can calculate average speed by dividing distance by travel time.
So the acceleration is the change in the velocity divided by the time.
Plugging our values into our formula for average acceleration we get a 103777 1 ms2. Speed timedistance Speed 401 40mph. Formulas for speed velocity and acceleration use change of position over time. Lets try the acceleration formula below.
