Question

7. Using the idea of Impulse, explain why a field goal kicker should 'kick through the ball', meaning extend their foot

as high up as possible at the end of the kick.

Answer 1

Impulse is the amount of force put on an object in a certain amount of time. Therefore when kicking a ball and "kicking through it" it extends the period of time this force is applied in turn increasing its impulse. Impulse is equal to change in momentum. momentum is equal to mass times velocity and since mass of the ball doesn't change therefore the velocity is increased and performance increased.
