![]() The concept of impulse tells you the effect the applied force has on changing the momentum of an object.Δt is the duration of time for which the force acts. The definition of impulse in physics is force multiplied by the duration for which the force acts.This is what is called an impulsive force.Back in the playground, you will have to apply some amount of force (a push) for a certain amount of time to get the swing moving. ![]() Thrust, which is basically the quantity of fuel that is thrown out of the rear of the rocket and the speed at which that propellant is flung out, is what determines the rocket's speed in relation to its weight. Specific impulse, or how much more push you get as you utilize that fuel, is the change in momentum per unit mass for rocket fuels. In the context of waves, another quantity is helpful to specify. These quantities and concepts transcend all of classical and quantum physics. The locations of the component particles or their momenta may be used to describe a physical system, and both formulations convey the same information about the system under discussion. On the other hand, a momentum space function's inverse Fourier transform is a position space function. In specifically, the Fourier transform of a function given in position space, f(r), yields the function in momentum space (p). Position and momentum's mathematical duality is an illustration of Pontryagin duality. A particle's momentum vector corresponds to its motion and has the units_ -1._ The collection of all momentum vectors that a physical system is capable of having is known as momentum space. In a nutshell, the concept of momentum tells you how much motion there is in a moving object.
