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.

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?

Practice:

Open the Force and Motion Simulation and select 3.2 Same Mass Collisions from the menu bar (top left). Use the Sim to gather evidence about the strength of the forces exerted during collisions between objects that have the same mass.
For Each Trial:
  1. Change the initial velocity of each object as described in your data table.
  2. Press RUN and observe how the velocity of each object changes due to the collision. Record your observations in the data table. For the effect, choose from the following options:
  • speed up
  • slow down
  • start moving
  • stop moving
  • change direction
  1. Press ANALYZE to determine the strength and direction of the force exerted on each object. Record in the data table.
  2. Repeat for 3.2 Different mass collisions

Which trial caused Object B to move the fastest after the collision? Why do you think this is?
CFS:
  • accurately describes the relationship between force, mass and velocity
  • describes the changes caused in an object

0

Which trial caused Object B to move the slowest after the collision? Why do you think this is?
CFS:
  • accurately describes the relationship between force, mass and velocity
  • describes the changes caused in an object

How does mass impact the velocity after a collision?
CFS:
  • accurately describes the relationship between force, mass and velocity
  • describes the changes caused in an object

0

How does increasing or decreasing the mass impact the force of a collision?
CFS:
  • accurately describes the relationship between force, mass and velocity
  • describes the changes caused in an object
