1.the quantity of motion of a moving body, measured as a product of its mass and velocity
2.the principle that the total linear or angularmomentum in any isolated system is constant,provided that no external force is applied
3.momentum = mass x velocity or p = mv
4. No one is quite sure why "p" is used for momentum. It likely came from the Latin word "petere" which means "go towards". They couldn't use "m" because that was already used for mass.
5. the motorcycle is going the right amount of speed more than the van
9.inelasic it would have no effect
10.the quantity of rotation of a body, which is the product of its moment of inertia and its angular velocity.
