100
A machine that uses two or more simple machines is called a ___________ machine. 
What is complex?
200
A device that makes work easier to do.
What is a machine?
200
This is the rate at which velocity changes.
What is acceleration?
200
Work divided by time tells us how to find this, which is the rate at which work is done. 
What is power?
200

200
Give an example of a complex machine that uses mainly human force to operate the simple machines in it. 
What is a bicycle?
300
This describes the speed and direction of a moving object.
What is velocity?
300
This is the rate at which work is done.
What is power?
300
Acceleration is equal to force divided by this.
What is mass?
300
When you ride a roller coaster, this is what makes your body rise out of its seat at the top of the hill. 
What is inertia?
300

400
An object is said to be in a state of this when all forces acting on an object balance each other. 
What is equilibrium?
400
This man described the Three Laws of Motion.
Who is Isaac Newton?
400
To find the mass of an object, divide the force by this.
What is acceleration?
400
This force keeps a satellite in orbit.
What is gravity?
400
Electricity and magnetism act on different objects by _______ or __________ the objects. 
What is pushing and pulling?
500
This is the force that pulls objects toward the center of the Earth.
What is gravity?
500
A device that changes the direction or the amount of force needed to do work.
What is a machine?
500
If the force on an object is 400 Newtons and the mass of the object is 200 kilograms, the acceleration is __________. 
What is 400 N/200 kg (Force/mass)-->2 meters per second squared?
500
Name four types of simple machines.
1)pulley

2)wheel and axle

3)lever

4)inclined planes

500
Describe Newton's Three Laws of Motion.
1) object at rest/motion stays at rest/motion until acted upon by an outside force

2) Force is equal to mass times acceleration

3) For every action, there is an equal and opposite reaction.
