Question

impulse = force x time
or
impulse = change in momentum x time

which equation is correct and explain the derivation plsss ​

Answer 1

Answer:

impulse = force × time

Explanation:

impulse means change in momentum

Answer 2

Answer:

the formula of

impulse = change in momentum × time

Explanation:

Start with Newton's second law.

F=ma

Integrate with respect to time.

∫Fdt=m∫adt

Define the left as impulse and give it the letter J. Apply the definition of acceleration and integrate.

J=mΔv

Bring the m into the delta and apply the definition of momentum.

J=Δp

Impulse is change in momentum. It's often written this way:

FaveΔt=Δ(mv)
