# How can I calculate the change of velocity?

Compute the acceleration.

You can do this by finding the second derivative of the position function, or the first derivative of a velocity function. Finding the derivative will give you the rate of change.

If you do not have a function you can plot the velocity points on a graph and find the slope of the line.

The change in velocity (Δv) can be calculated using the formula:

Δv = v_f - v_i

Where: Δv = Change in velocity v_f = Final velocity v_i = Initial velocity

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- What is the average speed, on #t in [0,5]#, of an object that is moving at #3 m/s# at #t=0# and accelerates at a rate of #a(t) =2t^2-2# on #t in [0,2]#?
