CEGEP Mechanics Tutoring
Build a reliable method for CEGEP mechanics: choose a system, sketch the motion or forces, and justify Newton’s laws or conservation before calculating.
Topics covered
Common difficulties
- Drawing forces on the selected object rather than forces it exerts
- Assuming a moving object must have a nonzero net force
- Applying conservation without checking external forces or work
How tutoring can help
We separate the physical model from the algebra. A free-body diagram includes actual interactions, not a generic force of motion. State axes and signs, write one principle, and only then substitute numbers. The final check asks whether direction, units and scale make physical sense.
Current codes and earlier search terms
These are subject crosswalks for the Science program, not transfer-credit decisions. The prefix matters: 201-SN1 is probability and statistics, while 203-SN1 is mechanics. Local codes and scope vary; your current outline is the reference.
| Subject | Current code | Earlier term |

An example that connects the ideas
A 2 kg object slides horizontally with a 10 N rightward applied force and 4 N leftward friction. Choose right as positive: ΣFₓ = 10 − 4 = 6 N, so aₓ = 6/2 = 3 m/s². The net force determines acceleration, not the object’s current speed.
A question to check understanding
Could it be moving left at that instant? Yes. Rightward acceleration can slow leftward motion before reversing it.

Review with a clear plan.
Practise selecting between kinematics, forces, energy and momentum without a chapter label. Explain why the selected model applies. Include graphs and qualitative questions as well as calculations; laboratory uncertainty is reviewed when included in your own section.
