State the principle of conservation of momentum.
Taught in: Conservation of momentum: the universe's strictest accountant, Explosions and recoil: zero before, zero after · 6 questions
Solve simple problems by applying the principle of conservation of momentum, including elastic and inelastic interactions between objects in one and in two dimensions.
The concept of coefficient of restitution is not required.
Taught in: Glancing collisions: conserve momentum along x and along y, Momentum in two dimensions: add the arrows, Elastic collisions: they part as fast as they met, Collisions in a straight line: signs are everything, Conservation of momentum: the universe's strictest accountant, Elastic or inelastic? Momentum always survives, kinetic energy might not, Explosions and recoil: zero before, zero after · 26 questions
Recall that an elastic collision conserves total kinetic energy, and that in such a collision the relative speed of approach equals the relative speed of separation.
Taught in: Glancing collisions: conserve momentum along x and along y, Elastic collisions: they part as fast as they met, Elastic or inelastic? Momentum always survives, kinetic energy might not · 10 questions
Understand that the momentum of a system is always conserved when objects interact, but that its kinetic energy may change.
