Question

Dervive an expression
expression for
newton second law ?​

Answer 1

Answer:

s=ut+1/2at^2

v=u+at

v^2+u^2=2as

Answer 2

Explanation:

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

F∝m(tv−u)

⇒F∝ma⇒F=kma(∵a=tv−u)

⇒F=ma(∵k=constant=1)
