Question

Q.1) Impulse is defined as the change in momentum of an
object when a force acts on the object for a time interval
Prove that change in momentum = impulse of force.​

Answer 1

Explanation:

Impulse…

is a quantity that describes the effect of a net force acting on an object (a kind of "moving force").

is represented by the symbol J (boldface).

is the product of the average net force acting on an object and its duration.

J = F∆t

is the force-time integral.

J = ⌠

⌡ F dt

is a vector quantity (since force is a vector and time is a scalar).

Impulse-Momentum Theorem

The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it.

J = ∆p

If mass is constant, then…

F∆t = m∆v

If mass is changing, then…

F dt = m dv + v dm

The impulse-momentum theorem is logically equivalent to Newton's second law of motion (the force law).
