Objective: PS2-1: Apply Newton’s Third Law, which states that for every action (force) in nature there is an equal and opposite reaction, to design a solution to a problem involving the motion of two colliding objects.

Question 1
1.
Scott and James work at a grocery store. They crashed the skateboard and the shopping cart two times. The shopping cart had more mass in Crash 2 than it did in Crash 1. Use the information in the diagram to answer.
In which crash did the skateboard experience a stronger force? Why?

Which crash experiences a greater force causing the motion for the satellite?
CFS:
accurately describes the relationship between force, mass and velocity
describes the changes caused in an object
Question 8
8.
Explain the forces on each object in a collision.
The diagram doesn’t tell you anything about the force on the skateboard. It only gives information about the force on the shopping cart.
The skateboard experienced the same force in both crashes. The shopping cart changed speed by the same amount in each crash, so the force on the skateboard was the same each time.
