Question

Second law of morion derive relation between force and acceleration

Answer 1

Answer:

Newton's second law of motion describes the relationship between force and acceleration. They are directly proportional. If you increase the force applied to an object, the acceleration of that object increases by the same factor. In short, force equals mass times acceleration.

Answer 2

Answer:

Consider a body of mass 'm' moving with initial velocity (u).Let F be a force acting on it for 't' second, so that the velocity changes to 'v'.

Initial momentum = =mu

Final momentum = =mv

change in momentum = = mv-mu

Rate of change of momentum =  

According to second of of newton F  

F

From equation of motion = a (acceleration)

Fma F = kma

Note : K is constant term.
