How does the inclined plane do your works faster and easier?
The reason that inclined planes allow us to reduce the force necessary to move items is because the work required to do both (Work = Force x Distance) is the same. When pushing up an inclined plane, the pusher only has to counteract the component of gravity that wants to slide the object back down the plane, instead of fighting against the entire force of gravity. Using an inclined plane decreases the force necessary to accomplish the task but increases the distance required for force against the vertical component. (An angled plane shortens the distance of travel overall).
What is a kite string attached to?
Kite string comes on wooden dowels, about half an inch to an inch in diameter, with the string wrapped around the dowel. One end of the string is attached to the kite, while the other end is attached to the dowel that you hold while flying the kite. The dowel allows you to easily release more string to let the kite go higher, or to reel the kite back in to you.
How does an inclined plane change the way work is done?
An incline plane allows less effort (pushing force) to be used to move a weight to a higher level without lifting straight up. You have to push it a longer distance, so ideally, the same amount of work is done, but really, due to friction more work is done. Maybe you can't lift a 500 pound barrel, but you can roll it up an inclined plane into the back of a truck.
What is a back to back stem and leaf chart?
A back to back stem and leaf chart consists of two stem and leaf charts, usually measuring related variables. The two charts share the same stem; in one chart the leaves go from right, at the stem, to left while in the other chart the leaves go from left to right as "normal".
