Question

According to Newton’s second law of motion, what is force equal to?
A) acceleration divided by mass
B) mass times acceleration
C) mass divided by acceleration
D) inertia times acceleration

Answer 1

Hello!

Here is your answer!

➡️ According to Newton's Second Law of Motion ==>

⏩ Force Is Equal to Mass Times Acceleration!

$(force = mass \: \times acclertion)$

Hence Second Option B is the Correct One!!
Now!

As we know that from Second Law of motion that

➡️p = mv
That is Rate of Change in Momentum = Mass × Velocity

So!

➡️ The change in momentum = mv – mu
➡️ The change in momentum = m (v – u).
The rate of change of momentum = m × (v – u)/ t
 
➡️ Or, the applied force, F ∝ m × (v – u)/t (v - u)t   
 F = km × (v – u)/t

F = kma     ---------------------------- (i)
 
Here, a  is the acceleration [i.e., a= (v – u)/t], which is the rate of change of velocity.

K is Constant!

Hope it helps u!

Answer 2

HEY BUDDY..!!!

HERE'S THE ANSWER..

_________________________

♠️ According to Newton's second law of motion " time rate of change of linear momentum is equal to force " , i.e

▶️ F = d ( P ) d t

⏺️ P is linear momentum , P = mass × Velocity

=> F = d ( m . v ) / d t

=> F = m . d ( v ) / d t

⏺️ We know time rate of change of velocity is Acceleration ( a )

=> [ F = m . a ]✔️✔️ ________( 1 )

♠️ According to Eqn ( 1 ) option [ B ] is correct , i.e mass times Acceleration .
