According to the law of conservation of in an isolated system the initial total momentum before a collision equals the final total momentum.?
momentum
What is momentum and how is it caculated?
momentum equals mass times velocity:]
What does the impulse momentum theorem state?
Impulse-momentum theorem
What could be described as impulse equals change in momentum?
Momentum = Mass x Velocity The change in momentum = (mass of the object x the end velocity) - (mass of the object x the beginning velocity)
Is momentum lost equals to momentum gained?
If you return to the same state of motion before you began gaining momentum, then momentum lost will be equal to momentum gained. I mean really, if you start out not moving with a momentum of 0 and end not moving with a momentum of 0, then of course there the bloody same. If you start at 0 and never stop moving, then obviously your not losing momentum so the statement is false.

momentum
Which is A student weighing 45kg runs down a slope and suddenly jumps with a speed of 3 m s onto a stationary skateboard The student and the skateboard move with a velocity of 2.7 m s What is the mass?
This can be modeled as a "collision" where momentum is conserved. Momentum equals mass times velocity (p = mv).Let's call the momentum of the student before the collision ps0 and the momentum of the skateboard before the collision pb0. Let's call the momentums after the collision ps1 and bs1.Since momentum is conserved, ps0 + pb0 = ps1 + bs1. Plugging the numbers for the momentum gives us:(45)(3) + (m)(0) = (45)(2.7) + (2.7)(m), where m is the mass of the skateboard.Simplified:135 = 2.7m + 121.513.5 = 2.7mm = 5So the mass of the skateboard is 5 kg.(Note that the units are all in kilograms, meters, and seconds they call match up in the calculations.)

What is the theorem that says that impulses equals changes in momentum?
Impulse-momentum theorem
What is the theorem that says that impulse that equals Change in momentum?
Impulse-momentum theorem
What do you need to have momentum?
based on the momentum formula, momentum equals mass times velocity, momentum can be achieved when something with mass is moving. P=mv
When objects collide the total initial momentum equals the total final momentum is called what?
this is called law of conservation of momentum
What is the mass of an object multiplied by its velocity?
The product of mass and velocity of an object is its momentum.
