Answer:

1. A ramp is an example of an inclined plane. Using an inclined plane makes it easier to move an object. It takes less force to move an object in an upward direction on an inclined plane than it does to lift the object straight up. Moving the object up an inclined plane requires moving it an increased distance.

2. A wedge is a triangular shaped tool, and is a portable inclined plane, and one of the six simple machines. It can be used to separate two objects or portions of an object, lift up an object, or hold an object in place.

3.Typical nuts, screws, bolts, bottle caps, and jar lids are tightened (moved away from the observer) clockwise and loosened (moved towards the observer) counterclockwise in accordance with the right-hand rule.

5.A wheel will start rolling when a force is applied and there is a resistive force or friction at the point of contact with the ground. The force may be a torque or a linear push on the wheel. Static friction causes the rolling motion. It is also called the traction of the wheel.

6.When an effort is applied to one end of the lever, a load is applied at the other end of the lever. This will move a mass upward. Levers rely on torque for their operation. Torque is the amount of force required to cause an object to rotate around its axis (or pivot point).
