... In Chapter 10 we defined the torque of a rigid body rotating about a fixed axis with each particle in the body moving on a circular path. We now expand the definition of torque so that it can describe the motion of a particle that moves along any path relative to a fixed point. If r is the positio ...

... Solution The pivot point is at the hinges of the door, opposite to where you were pushing the door. The force you used was 50N, at a distance 1.0m from the pivot point. You hit the door perpendicular to its plane, so the angle between the door and the direction of force was 90 degrees. Since = r x ...

... When the frequency of the driving force is near the natural frequency (w w0) an increase in amplitude occurs. This dramatic increase in the amplitude is called resonance. The natural frequency w0 is also called the resonance frequency of the system. At resonance, the applied force is in phase ...

... Newton’s three Laws of Motion were known. – An object at rest tends to stay at rest, an object in motion tends to stay in motion. – An object continues in its initial state of rest or motion with uniform velocity unless it is acted on by an unbalanced, or net external, force. (Physics 3rd Ed., Tip ...

... 7. If all objects fall to the earth at the same rate of acceleration due to gravity, why does a feather drop more slowly? Because the feather is not very dense and very flat. It has a lot of surface area. Because of this shape, the friction from the air particles it hits on the way down slow it down ...
