Is the total momentum always conserved between any two objects involved in a collision?

Answer 1

Generally speaking, Yes.

The caveat is that there must be no external forces acting (aka the collision takes place in a closed system).

These collisions are subdivided into elastic and inelastic collisions. For both total momentum and total energy (but not kinetic energy) are always conserved.

During elastic collisions total kinetic energy is conserved.

During inelastic collisions total kinetic energy is not conserved.

Yes, the total momentum is always conserved between any two objects involved in a collision, as long as no external forces are acting on the system. This principle is known as the conservation of momentum.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
