100
A push or pull on an object that can cause it to change motion.
What is force?
100
This type of energy can be seen in a motorcycle.
What is mechanical energy?
100
This is the ability to do work.
What is energy?
100
This is a simple machines that has a board or bar that rests on the turning point, the fulcrum.
What is lever?
100
This pulley changes the direction of the effort force. You pull the pulley in the opposite direction that you want the load to go.
What is a fixed pulley?
200
This is the force that pulls two objects toward one another because of their mass.
What is gravity?
200
This is the energy than an object has because of position, like at the top of a slide.
What is potential energy?
200
This is the result of a force moving an object.
What is work?
200
This simple machine uses a rope and a wheel to raise and lower objects.
What is pulley?
200
This pulley does not change the direction of the effort force. You pull the pulley in the same direction you want the load to go.
What is moveable pulley?
300
This is a force that slows the motion of moving objects.
What is friction?
300
This is the energy of motion, like a swing moving downwards.
What is kinetic energy?
300
Work does not occur.
What is pushing or pulling an object that does not move?
300
Stairs are an exmaple of this simple machine.
What is inclined plane?
300
This simple machine holds objects together.
What is a screw?
400
These are two effects that forces can have on motion.
What is gravity and friction?
400
This type of energy can be seen when you bake a cake.
What is chemical energy?
400
Work occurs.
What is pushing or pulling an object that moves?
400
A nail or a push pin is an example of this simple machine.
What is a wedge?
400
This simple machine has three classes.
What is a lever?
500
This is the tendency of a moving object to stay in motion or a resting object to stay at rest.
What is inertia?
500
This type of energy can be seen when you turn on a light bulb.
What is electrical energy?
500
These are used to make work easier.
What are simple machines?
500
A see-saw is an example of this simple machine.
What is a lever?
500
These machines use multiple simple machines.
