In a physics lab, you place a block on the top of a low-friction ramp as shown above. The block slides down the straight ramp, around a circular part at the bottom, up a straight ramp on the other side, and then shoots off the end. A, C are on the straight ramp and B is on the circular ramp (write down all points that apply. Put “none” if neither point applies) a) Is the apparent weight of the block less than the block’s weight at any of the points A, B and C? ____________ b) Is the apparent weight of the block larger than the block’s weight at any of the points A, B and C? ____________ c) Is the net force on the block zero at any of the points A, B, C and D? _____________ d) Is the tangential acceleration of the block zero at any of the points A, B, C and D?___

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
