Force and Friction Model
Product Code : SCL-AM-11114
Quick answer: The Force and Friction Model is a single demonstration model for lessons on friction as a force that opposes motion between surfaces in contact. It is used to compare the force needed to start and to keep up motion, and how extra load changes frictional resistance. The basic demonstration is mechanical. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How it is used in teaching
Friction acts along the surface of contact and opposes motion or attempted motion. Before an object moves, static friction grows to match the applied force up to a limit, F = mu_s N, where N is the normal reaction; once sliding begins, kinetic friction F = mu_k N is usually a little smaller, so less force is needed to keep the object moving than to start it.
Because both limits are proportional to N, adding load raises the frictional resistance in the same proportion. The model lets a class see these ideas directly and compare the force needed to start and maintain motion under different conditions.
- Place the model on a clean, level and stable table.
- Apply a slowly increasing pull, for example with a spring balance, and note the force at which motion just starts.
- Keep the object moving steadily and note the smaller force needed.
- Add load and repeat, then compare the results and discuss the coefficients of friction.
