Two ice skaters, initially at rest, push off against each other on a frictionless ice rink. How does the principle of conservation of momentum apply?

• The momentum of both skaters combined is always increasing.

• The momentum of both skaters combined is always decreasing.

• The total momentum of both skaters remains constant immediately before and after they push off, assuming no external forces act on them.

• The momentum of each skater is conserved only if the collision between them is elastic.
