Question

derive Newton's first law of motion from mathematical expression from the second law of motion​

Answer 1

⊕ANSWER⊕

• Newton's first law states that a body stays at rest if it is at rest and moves with a constant velocity unit if a net force is applied on it.

• Newton's second law states that the net force applied on the body is equal to the rate of change in its momentum.  

F = ma  

or F = m(v-u) / t

or Ft = mv - mu

• That is, when F = 0, v = u for whatever time, t is taken.

• This means that the object will continue moving with uniform velocity, u throughout the time, t.

• If u is zero than v will also be zero, i.e., object will remain at rest.
