Online CEGEP Mechanics Tutoring

Get help with CEGEP mechanics: kinematics, force diagrams, Newton’s laws, work, energy and momentum. Practise choosing a system and explaining which law applies, then find the guide for your college and course code.

Start with a concept you would like explained or a question you do not yet know how to begin. A course outline or an attempted solution can help if you have one. We confirm the level, topics and availability before booking. Tutoring sessions are currently offered in English. In-person options in Montréal

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

Your tutor can help you choose the object to study and draw its forces, or review a diagram you have started. Together, you can check the interactions, axes and signs, compare the relevant physical principles, build the equation and check whether the answer’s direction and units match the situation.

Current and former course codes

This table matches current and former codes by Science program subject. Your institution must confirm any transfer-credit equivalence. The prefix matters: 201-SN1 is probability and statistics, while 203-SN1 is mechanics. Course codes and topics can vary by institution. Check your current course outline.

Worked example

A 2 kg2\,\mathrm{kg} object moves horizontally under two applied forces: 10 N10\,\mathrm N to the right and 4 N4\,\mathrm N to the left, with no other horizontal forces. Choose right as positive. The net horizontal force is ∑Fx=10−4=6 N\sum F_x=10-4=6\,\mathrm N. Newton’s second law gives the horizontal acceleration ax=6/2=3 m/s2a_x=6/2=3\,\mathrm{m/s^2}. These forces determine the acceleration, not the object’s current velocity.

Check your understanding

Could it be moving left at that instant? Yes. Rightward acceleration can slow leftward motion before reversing it.

Prepare a CEGEP mechanics problem from the setup

These guides support the motion, force and conservation-law topics shared by many CEGEP mechanics courses. They are not an official review paper: match them to your section’s announced scope and permitted methods.

  1. Read the motion before choosing an equation

    Distinguish position, velocity and acceleration graphs, then check which slope or signed area answers the question.

  2. Draw the forces on one chosen object

    Name the source of each force, choose axes and justify the friction model before writing Newton’s second law.

  3. Choose between work, energy and momentum

    Define the system and time interval, then check the conditions for conservation instead of assuming them.

  4. Test your setup on mixed mechanics questions

    Write the diagram, signs and governing law before opening a solution; use the repair links for the decision you could not justify.

At each step: read the example, attempt a question before opening its solution, then redo a missed step without notes. Finish by applying the method to permitted practice from your own course.

Exam preparation

What to practise

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.

If your lab instructions include measurement uncertainty, use this lesson to distinguish uncertainty, discrepancy and percentage error before applying a propagation rule.

Choose a method before calculating

Start with what the question gives and what it asks you to find. These are useful starting points; a problem can require more than one method.

A position or velocity graph

A position-graph slope gives velocity; a velocity-graph slope gives acceleration. Signed area under velocity gives displacement. Do not assume constant acceleration unless justified.

Read motion graphs and build the equations

A collision followed by motion on a ramp or spring

Separate the collision from the later motion. Momentum conservation requires negligible external impulse during the chosen interval. Check nonconservative work before conserving mechanical energy.

Work, energy or momentum? Try explained collision problems

A beam or lever held at rest

Apply both force balance and torque balance. Choose a pivot and use the perpendicular lever arm.
