Correct Answer - Option 2 : F. dt
CONCEPT:
-
Impulse: A large amount of force acting on an object for a short interval of time is called impulse or impulsive force.
Numerically impulse is the product of force F and time dt.
Impulse = F. dt
EXPLANATION:
Impulse is calculated by doing the product of force F and time dt.
Impulse = F. dt
- So the correct answer is option 2.
The impulse of an object is equal to the change in momentum of the object.
Impulse = Δp =mΔv
F. dt = mΔv
\(F_{ext} = {Δ p \over Δ t}\)
This is Newton's Second Law of motion in momentum form.
