Question

State and prove second law of Newton Newton

Answer 1

Explanation:

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Answer 2

Newtons Second Law of Motion :-

The rate of change of momentum is directly proportional to the applied force,and takes place in the direction in which the force acts.

→ Force ∝ Change in momentum/ Time taken

→ F ∝ mv - mu/t

→ F ∝ m(v - u)/t

v - u/ t = a

→ F ∝ ma

→ F = k × m × a

Where k is constant,

→ F = ma

→ Force = Mass × Acceleration

First Law of Motion :-

A body at rest will remain at rest and a body in motion will continue in motion in a straight line with uniform speed,unless it is compelled by an external force to change its state of rest or of uniform motion.

Third Law of Motion :-

To every action there is an equal and opposite reaction.

Newton's first equation of motion :

• v = u + at

Newton's second equation of motion :

• s = ut + ½ at²

Newton's third equation of motion :

• v² = u² + 2as

Where,

• v = Final velocity
• u = Initial velocity
• s = Distance
• a = Acceleration
• t = Time
