Explanation:
According to Newton's second law of motion:
Force is directly proportional to
Change of momentum/time taken
Change of momentum= mv-mu
where m is mass, u is initial velocity and v is final velocity. so,
F∝mv-mu/t
F∝m(v-u)/t
F∝ma (a=v-u/t)
F=kma where k is a constant
In SI units the value of k will become one so the equation will be:
F=ma
