For example a car accelerates in 5 s from 25 ms to 3 5ms. A Dv Dt where a is acceleration Dv is the change in velocity and Dt is the amount of time it took for that change to occur. V D x D t.
A av 500 ms - 0 ms 10s - 0s a av 500 ms 10 s a av 50 m s s This can also be written as 50 ms 2.
For instance imagine youre a drag racer. V D x D t. Acceleration is the change in speed or velocity of an object over a certain time. Acceleration for an object is defined as the rate of change of velocity.
