PART I
  1. Select 2.1 Motionless Objects from the top-left menu bottom.
  2. Press RUN, then press ANALYZE to begin.
  3. Observe the initial velocity (start velocity) of the objects, record in the table below
---------------
  1. Go back to BUILD, press PREPARE FORCE to pause the Sim while you set up the forces described in your data table on the next page.
  2. Use the arrows in the Force panel in the bottom right corner of the screen to set up the required force on Object A, B, C, and D.
  3. Press EXERT FORCE to exert the forces and observe how each object’s velocity changes.
  4. Press ANALYZE. Record each object’s change in velocity

How is mass related to the acceleration of an object?
CFS:
  • Accurately identifies changes in the dependent variable by analyzing the movement of objects
  • Accurately describes the relationship between force, mass, and acceleration
  • Accurately identifies the strongest sources of evidence from the experimental data

Do you think the number of asteroid samples (adding or decreasing mass) a pod is carrying could make a difference to the pod's acceleration or direction of movement when the thrusters are activated?
CFS:
  • Accurately identifies changes in the dependent variable by analyzing the movement of objects
  • Accurately describes the relationship between force, mass, and acceleration

Independent Practice:

0

Background: The following three trials have the same mass and their initial velocity is the same. Model the force that would cause each velocity change.
  • For each, Insert a force arrow ‘During Force’, that would cause this velocity change.
Use the following table in answering the following questions.

0

Which trial has the greatest change in speed?

0

What is the relationship between the change in speed, and the amount of force applied?
CFS:
  • Accurately identifies changes in the dependent variable by analyzing the movement of objects
  • Accurately describes the relationship between force, mass, and acceleration
  • Accurately identifies the strongest sources of evidence from the experimental data

Exit Ticket:

2

Which object(s) do you think have the greatest mass? How do you know?
CFS:
  • Accurately identifies changes in the dependent variable by analyzing the movement of objects
  • Accurately describes the relationship between force, mass, and acceleration
