Overview
Free running
Watch the first attached video (you can watch any snippet of it)
- Describe the motion of one of the tricks (use phrases like "slowing down", "speeding up", "coming to a stop", "changing direction")
- Relate the change in the person's motion to an impulse acting on them
- Use the impulse-momentum theorem to explain how they stay safe as they do these tricks (the less force you experience, the safer you are)
2. Two Truck Collision
Watch the second attached video
- Describe the momentum of each truck before the crash (both how much and if it's positive or negative)
- Describe the momentum of each truck after the crash
- Compare the momentum of the two-truck system before and after the crash
- Is momentum conserved in this scenario?
