In an elastic collision between two objects,
Answer and explanation
Correct answer: C. both the total momentum and the total kinetic energy are conserved
- Step 1: An elastic collision conserves momentum and kinetic energy.
Answer
both the total momentum and the total kinetic energy are conserved.
Why not the others: only the total momentum is conserved: that describes an inelastic collision. only the total kinetic energy is conserved: momentum is also conserved in an isolated system. neither momentum nor kinetic energy is conserved: momentum is always conserved when no external force acts.
