Alex and Susan are ice-skating. At one point, Alex runs into Susan and holds on, and the two slide across the ice. After Alex collides with Susan, which of the following is true?
  1. Velocity is conserved.
  2. Energy is conserved.
  3. Momentum is conserved.
  4. Friction is conserved.
  5. Alex is conserved.
Explanation
Answer: C - In a collision between two objects, momentum is conserved. Energy and velocity are not conserved. Energy is usually released as heat or sound when objects collide, and the velocity will not remain the same due to the different initial velocities of the two objects.
