Question

What are possible formulas for impulse? Check all that apply. J = Fdeltat J = StartFraction force over change in time EndFraction J = Fdeltav J = StartFraction mass over change in time EndFraction J = mdeltav J = deltap

Answer 1

The possible formulas for impulse are as follows:

J = FΔt

J = mΔv

J = Δp

Answer: Option  A, E and F

Explanation:

The quantity which explains the consequences of a overall force acting on an object (moving force) is known as impulse. It is symbolised as J. When the average overall force acting on an object than such products are formed and in given duration than the start fraction force over change in time end fraction J = FΔt.

The impulse-momentum theorem explains that the variation in momentum of an object is same as the impulse applied to it: J = Δp J = mΔv if mass is constant J = m dv + v dm if mass changes. Logically, the impulse-momentum theorem is equivalent to Newton second laws of motion which is also called as force law.
