~Fairy+Tale~+Machines

Glossary:
A : air resistance: (page 1) when things fall gravity acts on them with a downward force.

D : distance- (page ) how far something has moved... measurement: meters or kilometers
 * it depends on speed, size, and shape of an object

F:

fixed pulley- (page 2) dosen't rise or fall with the force that is being pulled.

force-( page ) a push or a pull applied to an object that will cause it to start moving, stop moving, or change it's speed or direction.

I : inclined plane- (page 5) a simple machine for elevating objects; consists of plane surface that makes an acute angle with the horizontal

L: lever- (page 6)
 * a rigid bar pivoted about a fulcrum
 * a simple machine that gives a mechanical advantage when given a fulcrum
 * there are 3 types of levers~
 * 1) the fulcrum is the wheel (class 1)
 * 2) the load is in the center of the barrow (class 2)
 * 3) the load is at the end of the lever (class 3)

P: pulley- (page 2) a simple machine consisting of a wheel with a groove in which a rope can run to change the direction or point of application of a force applied to the rope

power- (page 6) the rate of doing work or moving energy. Power is equal to energy (or work) devided by time. P=w/t

M: machine- (page 2) device that makes work easier; changes the size and/or direction of the exerted force. *There are simple machines and compound machines*

morable pulley- (page 2) rises and falls with the force that is being pulled.

S: screw- (page 2)
 * a simple machine of the inclined-plane type consisting of a spirally threaded cylindrical rod that engages with a similarly threaded hole
 * cause to penetrate, as with a circular motion; "drive in screws or bolts"

simple machine- (page 2) an out powered machanical device that accomplishes a task with only one movement.

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

wheel and axle- (page 4) The wheel and axle is a simple machine. A wheel and axle is a modified lever of the first class that rotates in a circle around a center point or fulcrum. The larger wheel (or outside) rotates around the smaller wheel (axle )

work- (page 4)- ~constructing~ using a force to move an object a distance (when both the force and the motion of the object are in the same direction)
