Impulse-momentum theorem
Impulse-momentum theorem
Momentum = Mass x Velocity The change in momentum = (mass of the object x the end velocity) - (mass of the object x the beginning velocity)
momentum equals mass times velocity:]

Impulse-momentum theorem
Impulse-momentum theorem
Wavelength equals Planck's Constant divided by momentum.
The law of Conservation of Momentum is the result of The Law of Equilibrium, Force equals zero. When Force is zero, Momentum is constant, dP/dt = f = 0. dP/dr = 0 gives P = k a constant.
Momentum = Mass x Velocity The change in momentum = (mass of the object x the end velocity) - (mass of the object x the beginning velocity)
It is the impulse which equals the change in momentum.
Impulse equals change in momentum. "Apex" The final momentum of any object (or collection of objects) must equal to its initial momentum plus any impulse imparted to the object (or collection of objects).
Momentum is the quantity that is conserved in this case. Conservation of Momentum is a consequence of Conservation of Energy, which equates to the sum of forces equals zero. 0 = f1 + f2 = dp1/dt + dp2/dt = d(p1 +p2)/dt = d(constant)/dt =0.
A modified form of Planck's constant called h-bar (ℏ), or the reduced Planck's constant, in which ℏ equals h divided by 2π, is the quantization of angular momentum. For example, the angular momentum of an electron bound to an atomic nucleus is quantized and can only be a multiple of h-bar.
Impulse is the change in momentum. Therefore Impulse is only equal to momentum if the initial momentum was equal to zero. Its the same phenomenon as position and displacement. Impulse= final momentum-initial momentum= mv - mv_0= Force * Time Where m is the mass and v is the velocity.
