Question

define to find the law of motion and derive f=ma

Answer 1

Answer:

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∝TimeChangeinmomentum. F∝tmv−mu.

Answer 2

Answer:

• 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∝ Time/Change in momentum

F∝ t/mv−mu

F∝m( t/v−u )

⇒F∝ma⇒F=kma(∵a= t/v−u )

⇒F=ma(∵k=constant=1)
