Impulse, that has been applied to an object, is seen to yield an original vector change in its direct impulse, also in the attendant direction. The SI unit of impulse is the Newton second (Ns), and the dimensionally original unit of impulse is the kilogram cadence per second (kg ⋅ m...

Using the definition of impulse, the change in momentum of car 1 is given by Δp1 = F1Δt, where F1 is the force on car 1 due to car 2, and Δt is the time the force acts (the duration of the collision). Intuitively, it seems obvious that the collision time is the same for ...
The Momentum and Impulse lab uses a laboratory cart to investigate the relationship between the impulse exerted on a constant mass and the resulting change in the momentum of the mass. It is part of Polyhedron Physics Plus, a set of 24 iPad apps for use in the classroom. To see how they...

For instance, in ice hockey, the puck experiences a significant impulse during a slap shot. A considerable force acts on the puck for less than a second, causing a change in the ball's velocity and hence its momentum. The difference in momentum is added to the initial momentum to calculate...

The net specific impulse based on net impulse measurement (direct-velocity measurement) was 67–147 s, which was 28%–60% of the Endo-Fujiwara theory. The difference between the two specific impulses is due to the momentum transfer on the sidewall of the tubes that was neglected in the ...
