Question

derive first law and second law of motion​

Answer 1

Answer:

first law. according to first law a body is in the rest remain at rest and a body is in the motion remins in motion until extrnal force is applied on it

second law === the Celebration of an object is directly proportional to the magnitude of the net force in the same direction of net force and inversely proportional to the mass of the object

Answer 2

Explanation:

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.
