# why does a baseball travel fast?

why does a baseball travel fast? for example compared to a football its way faster

Relevance

Newton's Second Law. If you apply a force to something, it acclerates. If that something is light, it accelerates fast, and if it is heavy, it accelerates less. A football weighs a LOT more than a baseball (comparitively). Since the average human arm can only deliver x amount of force, the acceleration depends on the ball. Assuming the football is twice as heavy as the baseball, then the acceleration can be found like this:

Acceleration = Force / Mass

a=F/m

so for the baseball of mass m:

a1=F/m

=x/m

and for the football of mass 2m:

a2=F/m

=x/2m

=0.5(x/m)

=0.5(a1)

So you can see, that since there is less acceleration the ball must therefore end up going at a slower speed.

Cheers.
