10 Circular Motion
... greater distance in one rotation than a point near the center. • The linear speed is greater on the outer edge of a rotating object than it is closer to the axis. • The speed of something moving along a circular path can be called tangential speed because the direction of motion is always tangent to ...

Static Friction
... object. The normal force is defined as the perpendicular component of the force exerted by the surface. In this case, the normal force is equal to the weight of the object. Once the box starts to slide, you must continue to exert a force to keep the object moving, or friction will slow it to a stop. ...

... average speed was 80 km/h, even though you might have been stuck in a traffic jam for some of the time. When your motion is speeding up and slowing down, it might be useful to know how fast you are going at a certain time. For example, suppose the speed limit on a part of the above trip was 50 km/h. ...

... for each of the n ’half trips’ (not round trips), starting with n = 0 to go down the ramp the first time. We also have to remember that what we calculated is how far the block goes up the ramp for a given trip, it has to go back down the same distance. The total distance is then twice the sum of all ...
