Collisions
Collisions
Why is there damage done when a crash occurs? How do the colliding objects interact?
Essential Question: What causes a rocket to take off?
Newton’s Third Law states that “for every action, there is an equal and opposite reaction.” In a collision, energy is transferred from one vehicle to the other. The magnitude of this energy depends on factors such as speed, mass, and protections against collision.

Lab: Newton's 3rd Law
Watch the video to complete the lab. Pause the video when the camera zooms in on the measurements. It may be a bit hard to read, but you should be able to see it and write it down.
In the first part, the student on the left pulls on the spring scale while the student on the right stays completely still. What are the readings?
In the second part, both students are pulling at the same time. What is the reading on both scales now!?
