why does rate of change of momentum correspond force?

Asked by harshilashwin | 22nd Sep, 2008, 12:01: AM

Expert Answer:

this is because

F = m x a , where F is force, m is mass , a is accelearation whose formula is dv / dt (rate change of velocity wrt time) whereas momentum P = m x v therefore rate change of momentum means

dp / dt which is equal to m x dv / dt hence rate change of momentum is called as force.
