Impulse And Impulsive Force

Impulse And Impulsive Force

	Impulse = change in momentum \((\text{kgms}^{-1})\)
	\(Ft=mv-mu\)

	Impulsive force = rate of change of momentum (\(\text{N}\))
	\(F=\dfrac{mv-mu}{t}\)

	Newton's Third Law of Motion
	For every action there is a reaction of equal magnitude but opposite direction

Time vs impulsive force
- \(F=\dfrac{mv-mu}{t}\)
- \(F\propto\dfrac{1}{t}\)
- When t \(\uparrow\), F \(\downarrow\)
