... beneath it. (b) Would this value change as the plane moves away from the same point? Explain. 38. A ball of mass 175 g is attached to a string and it is twirled around in a horizontal circle of radius 75.0 cm at a frequency of 2.00 Hz. It revolves clockwise as seen from above. (a) Find the magnitude ...

... Forces and the Laws of Motion Think about the different ways in which you could move a textbook. You could touch it directly and push or pull it, or you could tie a string around it and pull on the string. These are examples of contact forces. A contact force exists when an object from the ex ...

CHAPTER TWO Motion
... Motion is one of the more common events in your surroundings. You can see motion in natural events such as clouds moving, rain and snow falling, and streams of water, all moving in a never-ending cycle. Motion can also be seen in the activities of people who walk, jog, or drive various machines from ...

In fact, this would indicate that if nothing is pushing an object its velocity will not change. Galileo was perhaps the first to recognize that c ...

Vectors [1
... This is more challenging, but its not THAT hard! You need to separate your system into horizontal and vertical parts. You also need to realize that in the horizontal part, Tim moves at a constant speed, but the water dropped by Bill will accelerate. Other than that, everything else is the same and t ...

Equality of Column Vectors
... A scalar quantity has a magnitude but no direction. For example, a pen may have length "10 cm". The length 10 cm is a scalar quantity - it has magnitude, but no direction is involved. In vectors, a fixed numeric value is called a scalar. We can increase or decrease the magnitude of a vector by multi ...
