1.23 use the relationship between force, change in momentum and time taken: force = change in momentum ÷ time taken

Formula:
Force = change in momentum
                     time taken

This equations is used with questions like "How much force does the driver feel during this collision"

• The change in momentum would go from a velocity to a standstill as it collides with a stationary object

The formula can be rearranged to form:

Change in momentum = force x time taken

Time taken = change in momentum

                                 force
