Full Answer

Frictional forces are affected by the texture of the surfaces and the amount of force pushing them together. The angle and position of the objects affects the amount of frictional force. If an object is sitting flat against an object, then the frictional force is equal to the object's weight. If the object is pushed against the surface, the frictional force is increased and becomes greater than the object's weight. Objects pulled away from the surface and those at an incline with the surface have less frictional resistance.

    How is a ruler different from a straightedge?

    A:

    The primary difference between a ruler and straightedge is that a ruler is a measurement device, whereas a straightedge is a tool for drawing or viewing straightness. A ruler is a straightedge with some scale on it so that it can act not only as a straightedge, but also as a device to measure distance. Therefore, a ruler is a straightedge, but a straightedge is not necessarily a ruler.

    How do you draw a rectangular prism?

    A:

    To draw a rectangular prism, determine what direction you want it to face, draw the two ends and connect them with lines using the vanishing point and other principles of perspective. A prism has perfect edges and faces, so you should use a ruler.
