L7 WS1 – Friction
... Friction is all around us. It is because of friction that erasers work for us. There is friction working against us when we ride a bike or skateboard, roller blade, run, play tennis, cut our food and use a nail file to shape our nails. These are just a few examples of friction at work. There are sev ...

... An object sliding down an incline has three forces acting on it: the normal force, gravity, and the frictional force. • The normal force is always perpendicular to the surface. • The friction force is parallel to it. • The gravitational force points down. If the object is at rest, the forces are the ...

... In general, friction is the force that slows down the motion of an object. The force of friction is directed along the surface of contact between the object and surface and directed opposite to the direction of motion of object. We deal with: a) Static friction ( fs) This exists when the object is a ...
