Question

state Newton's second law of motion write relationship F=ma​

Answer 1

Answer: according to the newton's second law of motion the rate of change of momentum is directly proportional to applied force

let a body of mass m  moving with a velocity of v and u m/sec respectively

so change in momentum = m1v1-m1u1

and rate of change of momentum is m1v1-m1u1/t (t is time taken)

so according to newton's law

F∝ m1v1-m1u1/t

F∝m(v-u/t)

v-u/t = acceleration (a)

F = k ma

k is constant of proportionality whose value is 1

so F = ma

Answer 2

Answer:

according to Newton's second law of motion the rate of change of momentum of a body is proportional to the unbalanced force acting on it and takes place in the direction of the force
