What role does mass play newtons law?

Answer 1

Newtons (second) and most powerful law, force(f) = mass(m) * acceleration(a)

and its derivatives, deal with the changes on a body when forces are applied to it.

Example: impulse - velocity change

A force of 1000 newtons is applied to a mass of 100 kilograms for 10 seconds,

calculate the velocity change(vc).

f = m * a , but a = velocity change(vc) / time(t),

so:

f = m * (vc / t)

so:

vc = (f * t) / m

so:

vc = (1000 * 10) / 100

vc = 100 metres per second
