Speed and Collisions
LEARNING TARGET: I can explain the relationship of how speed affects the forces involved in a collision.
CH Q
Does vehicle speed affect the forces involved in a collision?
VOCAB:
forces
push or pull that changes motion

3. DISCUSSION
1. How do you know forces are acting on objects?
Although invisible, forces cause the object to move differently

4. PROCEDURE AND DATA
MATERIALS:
PROCEDURE: Read on pg. E and summarize
DATA: WS Effect of Ramp Height

5. POST DISCUSSION
At bottom the of the hill, which track will the roller coaster be going faster (most energy)?
Low or high track?
higher track --the higher the release point on hill the higher energy at the bottom (remember: Gravitational Potential Energy)

6. POST DISCUSSION
All things being equal, which ball will be moving faster? Explain A B
B – there is more Gravitational Potential Energy to be converted into Kinetic Energy

7. Which car was going faster?B
What is the evidence to support your answer?
B -- the faster the object is going, the more kinetic energy it has to do damage

8. ANALYSIS
- Discuss and answer Q 1, 2 & 4 on pg. E 18
ANS CH Q
Does vehicle speed affect the forces involved in a collision? A:
yes, the faster it is moving the more energy (force) it has to transfer
