Question

show that the rate of change of momentum is equal to the product of mass and acceleration.
answer in detail long answer(5 marks)

Answer 1

To prove- F= ma
since,
Through Newton second rule equal to change in momentum per unit time.
F= force
M = mass
U = initial velocity
V= final velocity
T= time
F= mv-mu/t
=m (v-u)/t ............(1)
from first equation of motion,
a=v-u/t
putting value of v-u/t in equation (1)
F=ma
Hence proved.
