state the law of Momentum and derive.what is the S.I.unit of momentum.
(please don't give irrelevant answers)
Answers
Answer:
In SI units, momentum is measured in kilogram meters per second (kg⋅m/s). Newton's second law of motion states that the rate of change of a body's momentum is equal to the net force acting on it.
Answer:
Law of conservation of momentum states that when two objects collide with each other , the sum of their linear momentum always remains same or we can say conserved and is not effected by any action, reaction only in case is no external unbalanced force is applied on the bodies.
Let,
m
A
= Mass of ball A
m
B
= Mass of ball B
u
A
= initial velocity of ball A
u
B
= initial velocity of ball B
v
A
= Velocity after the collision of ball A
v
B
= Velocity after the collision of ball B
F
ab
= Force exerted by A on B
F
ba
= Force exerted by B on on A
Now,
