# Physics- force and momentum watch

1. Why does a ball travel further when you hit it with a bat harder (larger force and the mathematical equations for it)?
2. Either handle using Impulse (Average force times time) or momentum together with coefficient of restitution. There are other approaches involving such things as centre of percussion but a question is needed for context and level really,

Honestly, there are a lot of explanations.

The force exerted on the ball is dependant on the person's strength, so if F is large, then ∆v will be greater, for the same m & ∆t.

F * ∆t = m * ∆v

F ∝ ∆v

So the initial velocity of the ball will be greater and hence greater range.

Do note that, if the time of contact (∆t) of the ball with the bat, is large, also then the ∆v will be large, for the same m and F.
