explain about the Newton's 2nd law and derivation of F=ma,?
Answers
Answer:
Newton’s Second Law of Motion is defined as Force is equal to the rate of change of momentum. For a constant mass, force equals mass times acceleration.
p1 = m × u
The final momentum
p2 = m × v
The change in momentum can be expressed as
p2 – p1 = (m × v) – (m × u)
p2 – p1 = m (v – u)
But we know that the rate of change of momentum with respect to time is proportional to the applied force.
The applied force
F ∝ [m (v – u)]/t
F ∝ m × a
as acceleration (a) = rate of change of velocity with respect to time.
F = k × m × a
i hope this is your answer
Answer:
states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. The momentum of a body is equal to the product of its mass and its velocity.
