motion
random
100
any of the basic mechanical devices for applying a force, such as an inclined plane, wedge, or lever.
what is a simple machine?
100
forces that cause a change in the motion of an object.
what is an unbalanced force
100
first law of motion
what is every object in a state of uniform motion will remain in that state of motion unless an external force acts on it.
100
the amount of matter in an object
what is mass?
100
the measure of an objects distance during a unit of time
what is speed?
200
a plank or ridged beam that is free to rotate on a pivot. It is perfect for lifting or moving heavy things. It is a very useful simple machine, and you can find them everywhere.
what is a lever?
200
a force that causes no motion between objects
what is a balanced force
200
2nd law of motion
what is force equals mass times acceleration [ 
].
200
the force with which something moves
what is momentum?
200
any change in the speed or direction of an object's motion
what is acceleration
300
a triangular shaped tool, and is a portable inclined plane, and one of the six classical simple machines.
what is a wedge?
300
the resistance caused when one object is moved in contact with another
what is friction
300
newtons 3rd law
what is for every action there is an equal and opposite reaction.
300
A measure of the force of gravity on an object
what is weight
300
upward force on an object
what is a lift?
400
onsisting of a wheel over which a pulled rope or chain runs to change the direction of the pull used for lifting a load.
what is a pulley?
400
the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
what is gravity
400
when did izaac newton die
when was March 31, 1727
400
a change of position of an object
what is motion
400
the force that slows an object down
what is a drag?
500
the inclined-plane type consisting of a spirally threaded cylindrical rod that engages with a similarly threaded hole.
what is a screw?
500
likely to maintain a state of rest unless acted upon by an external force
what is inertia?
500
what did izaac newton do for a living
Sir Isaac Newton FRS PRS was an English mathematician, physicist, astronomer, theologian, and author.
500
the measure of the speed and the direction of an object
what is velocity?
500
the force when a car just starts moving
what is a thrust?
