Which of the following scenarios demonstrate the conservation of either linear or angular momentum?
1. A parent pushes a merry-go-round and, consequently, it spins faster.
2. From opposite sides of a room, two identical balls of putty move toward each other, without friction, at the same velocity, and eventually, they collide; the result is one ball of putty with zero velocity.
3. A penny is dropped from the top of a building and its velocity increases as it falls due to the acceleration from gravity.
4. An ice skater tucks in her arms during a spin and her angular velocity increases.
