Document Summary

Friction: static friction surfaces are not moving relative to each other. Static friction force can change but it has an upper limit. Once your applied force exceeds the maximum static friction force that is available, the net force becomes non-zero and motion can occur: kinetic friction is always less than the maximum static friction. Third rule of motion: whenever two objects interact, they always exert equal but opposite forces on each other, nh on c = -nc on h (act on different objects and thus don"t cancel each other out) Lecture notes: force is an interaction between 2 bodies, an object and an agent, a vector, something which can be produced with or without contact, something without which there is no acceleration. If it is going really fast then slowing down, it is accelerating in the upwards direction (fnet is in the upwards direction)
