Table 6.1 Approximate Coefficients of Static and Kinetic Friction. Equation 6.1 and Equation 6.2 include the dependence of friction on materials and the normal force. The direction of friction is always opposite that of motion, parallel to the surface between objects, and perpendicular to the normal force. For example, a free body diagram of a block sitting upon an inclined plane can illustrate the combination of gravitational force, "normal" force, friction, and string tension.

Since the bag isn't moving up or down ... In both cases the Tension and the Normal force are doing two 'jobs'. They are supporting the weight of the object, but also providing a sideways acceleration.Don't confuse any of this with normal force. Normal force is an opposing force to gravity exerted in the upward direction by the ground. It's from Newton's 3rd law, which in simple terms says "every action has an equal and opposite reaction." The normal force is also always at a right angle. If another force is acting upwards on an object, then less normal force needs to be exerted by the surface to make the object stay in equilibrium. For example, if an object has a downwards weight of 25 N and a tension is pulling it up by 10 N, the upward normal force required to keep the net force 0 would be 15 N.When we derive the formulas for centripetal acceleration, we are only looking at a single force at a time. The centripetal force will not increase the speed of the ball by itself; it will only change the direction of the velocity just enough to make the ball travel in a circular path. If there are no other forces than the centripetal force, the speed will be constant.Calculate the normal force and the maximum frictional force that can be exerted on the car.
