Instructions:- Roll Object A toward Object B and observe how the objects change velocity when they collide. Record your observations in the data table
- For Effect: Object A and Effect: Object B. choose from the following options:
- speed up, slow down, start moving, stop moving, change direction
- Based on the velocity changes, infer the direction of the force (if any) acting on each object and record it in the table for Force direction: Object A and Force direction: Object B. Choose from the following options: • left, right, none
- Repeat these steps for all three collisions.

Lab Reflection Questions:
In test 1-3, what evidence can you find to support why ‘Object B’ has the greatest change in velocity during one of the trials?
CFS:- accurately identifies the changes to each object in a collision
- accurately describes the relationship between force, mass and velocity in a collision
- accurately identifies the strongest sources of evidence from the experimental data
