Tension and friction force
This simulation is useful to see how is the resistance force generated by friction when pulling a block horizontally? How are the tension and friction forces while the block is still? What would happen if the tension force is greater than the friction force?
Normal and frictional forces
This simulation helps us to see what the resistance force generated by friction is like when pushing a block horizontally? What are the forces of thrust and friction like while the block is still? What would happen if the force of thrust is greater than the force of friction?
