A: 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.
B: FORCE
Momentum =mass x velocity.Rate of change of momentum =change in momentum/time ie mv-mu/t ie same as m (v-u)/t which is same as m x a where m is mass and a is accelaration .ie rate of change of momentum is force .it can be written as M^1L^1T^-2
C: A rocket works by expelling gases from one end at a very high velocity. ... Due to the principle of conservation of momentum the body of the rocket is pushed forward. If both the momentum of the gases as well as that of the rocket are added the sum is zero.
