1 Whenever an interaction occurs in a system, forces occur in equal and opposite pairs. Which of the following do not always occur in equal and opposite pairs? 1. Impulses. 2. Accelerations. 3. Momentum changes. 4. All of these occur in equal and opposite pairs. 5. None of these do.

2 Whenever an interaction occurs in a system, forces occur in equal and opposite pairs. Which of the following do not always occur in equal and opposite pairs?

3 Which would be more damaging? 1. Driving into a massive concrete wall. 2. Driving at the same speed into a head- on collision with an identical car traveling toward you at the same speed. 3. They are equivalent.

5 Strictly speaking, when a gun is fired, compared with the momentum of the recoiling gun, the opposite momentum of the bullet is 1. less. 2. more. 3. the same.

7 An ice sailcraft is stalled on a frozen lake on a windless day. A large fan blows air into the sail. If the wind produced by the fan strikes and bounces backward from the sail, the sailcraft will move 1. to the left (backward). 2. to the right (forward). 3. not at all.
