Answer:

According to Newton’s 2nd Law of motion, the rate of change of linear momentum of a body is directly proportional to the applied external force and in the direction of the force.

It means that the continuing momentum will change faster when a bigger force is applied.

Consider a body of mass m’ moving with velocity v.

The continuing or linear momentum of a body is given by:

p = mv

Now According to Newton’s 2nd Law of Motion:

Force is directly proportional to rate of change of momnetum, that is

F α dp/dt

F = k dp/dt

F = k d(mv)/dt

F = k md(v)/dt

F = k ma

Experimentally k =1

F = k ma

Which is the required equation of force.

Answer 2

Answer:

According to Newton's second law we know that mv-mu/t is proportional to force applied. so we can write that m(v-u)/t = f but (v-u)/t = a We can write that ma = f i.e f = ma
