Question

state newtin second law of motion and also derive F=ma
​

Answer 1

Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. In equation form, Newton's second law of motion is a=Fnetm a = F net m .

Answer 2

Newton's second law of motion states that the impact produced by a moving object depends upon its mass and velocity.

Explanation:

derivation :-

the change in momentum = p2-p1

directly proportional to mv - mu

or. m(v-u)

the rate of change of momentum is directly proportional to m(v-u)/time

what the applied force,F is directly proportional to m(v-u)/t

to remove the proportion we use proportionality constant 'K'

so F = Kma where value of constant k is equal to 1.

so F = ma

unit of force is kg metre/ second square
