Try to predict what would happen in the following scenarios, explain your reasoning: 1. Two identical objects that can stick together moving towards each other at the same speed 2. Two identical objects that can stick together, one at rest, the other moving towards it 3. A heavy object and a lighter one that would bounce from each other. The small one starts at rest, the big one is moving towards the small one 4. two identical objects that would bounce from each other. One at rest, the other moving towards it. 5. A heavy object and a lighter one that would bounce from each other. The heavy one starts at rest, the small one is moving towards the heavy one. ( you can use a basketball and a tennis ball)

Question
**Exercise: Predict Outcomes in Collision Scenarios**

- **Objective:** Analyze different collision scenarios and predict the outcomes, providing explanations for each prediction.

1. **Scenario 1:**
   - Two identical objects that can stick together are moving towards each other at the same speed.
   - *Prediction & Explanation:* When these objects collide, they will stick together, and since they have equal and opposite momentum, they will come to rest. This is due to the conservation of momentum and the fact that their combined velocity becomes zero.

2. **Scenario 2:**
   - Two identical objects that can stick together, one at rest, the other moving towards it.
   - *Prediction & Explanation:* When the moving object collides with the stationary object, they will stick together and move with half the initial speed of the moving object. This is due to the conservation of momentum, where the total momentum before collision equals the total momentum after collision.

3. **Scenario 3:**
   - A heavy object and a lighter one that would bounce off each other. The small one starts at rest, and the big one is moving towards the small one.
   - *Prediction & Explanation:* After collision, the lighter object will move away with greater speed compared to the initial speed of the heavy object, while the heavy object will continue moving in the same direction but at a reduced speed. This outcome follows from conservation of momentum and kinetic energy.

4. **Scenario 4:**
   - Two identical objects that would bounce from each other. One at rest, the other moving towards it.
   - *Prediction & Explanation:* The moving object will come to rest after the collision, while the initially stationary object will move with the initial speed of the moving object due to conservation of momentum and kinetic energy (elastic collision).

5. **Scenario 5:**
   - A heavy object and a lighter one that would bounce from each other. The heavy one starts at rest, while the small one is moving towards it (e.g., basketball and tennis ball).
   - *Prediction & Explanation:* The lighter object will bounce back with a slightly reduced speed while transferring some of its momentum to the heavier object, causing the heavier object to move slightly. The change in velocities will reflect conservation of momentum and kinetic energy principles.

*Note: These explanations assume idealized conditions such as no external forces and perfectly elastic or perfectly inelastic collisions as specified.*
