Question

25. (a) State Newton's second law of motion. Derive, its mathematical expression.​

Answer 1

Answer:

Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.

Answer 2

Explanation:

Newton’s second law of motion states that the force exerted by a

Newton’s second law of motion states that the force exerted by a body is directly proportional to the rate of change of its momentum. For a body of mass ‘m’, whose velocity changes from u to v in time t, when force ‘F’ is applied.F∝ TimeChange in momentum

momentum

momentum

momentum F∝ t

momentum F∝ tmv−mu

momentum F∝ tmv−muF∝m( tv-u )

)⇒F∝ma⇒F=kma(∵a= tv−u )

)⇒F∝ma⇒F=kma(∵a= tv−u )⇒F=ma(∵k=constant=1)
