Q: Which of the following statements about the conservation of momentum is true?

Solution: Momentum is conserved in all types of collisions, provided no external forces act on the system.

Steps: 5

Step 1: Understand what momentum is. Momentum is the product of an object's mass and its velocity.
Step 2: Learn about collisions. Collisions can be elastic (objects bounce off each other) or inelastic (objects stick together).
Step 3: Know the principle of conservation of momentum. This principle states that in a closed system (no external forces), the total momentum before a collision equals the total momentum after the collision.
Step 4: Apply the principle to different types of collisions. In both elastic and inelastic collisions, if no external forces are acting, momentum is conserved.
Step 5: Conclude that the statement about momentum conservation is true when no external forces are present.
