Force and Motion in Two Dimensions - juan-roldan
... Now you will use your skill in adding vectors to analyze situations in which the forces acting on an object are at angles other than 90°. Recall that when the net force on an object is zero, the object is in equilibrium. According to Newton’s laws, the object will not accelerate because there is no ...

... Friction is a force that opposes the motion of two objects that are touching each other. It does this by creating temporary electromagnetic forces between the contact points of the two surfaces. Friction acts in a direction parallel to the surfaces in contact and opposing the motion. The force exert ...
