the act of changing position from one place to another.
What is motion?
100
a force of attraction between two objects.
What is gravity?
100
the transfer of energy by a force that moves an object.
What is work?
100
this law states that for each action, there is an equal or opposite reaction.
What is Newton's Third Law?
100
This simple machine uses a rod that pivots around a fulcrum.
What is a lever?
200
the measure of the distance that on object moves in a given amount of time.
What is speed?
200
a push or pull on an object.
What is force?
200
a device that makes work easier.
What is a machine?
200
The law suggests that objects are lazy.
What is Newton's first law?
200
This type of machine uses a rod as a type of fulcrum around which a wheel rotates. Its mechanical advantage is directly related to the radius of the wheel.
What is a wheel and axle?
300
the tendency of an object to resist a change in its motion.
What is interia
300
the force of gravity on an object.
What is weight?
300
a machine that does work with one motion.
What is a simple machine?
300
This law explain how rockets work.
What is newton's third law?
300
This type of simple machine uses gravity to make work easier.
What is an inclined plane ?
400
an increase in the speed of an object.
What is acceleration?
400
a force that opposes motion when two surfaces rub together.
What is friction?
400
the amount of force applied to a machine.
What is effort force?
400
Force equals mass times acceleration.
What is Newton's second Law?
400
This type of pulley has the greatest mechanical advantage.
What is a block and tackle pulley?
500
The average rate at which an object moves from one location to another.
What is average speed?
500
the amount of matter in an object.
What is mass?
500
The force that resists motion in a simple machine?
What is resistance force?
500
This law explains why it is hard to stop something heavy, and why something light can also have a lot of force if it is moving fast enough.
What is Newton's Second Law?
500
This simple machine is made of an inclined plane wrapped around a pole.
