Forces
What is the word for something that changes the motion or shape of an object?
Force
What is the force called that slows down two objects rubbing together?
Friction
What is the property of matter that causes objects to be lazy and prefer to travel in straight lines?
Inertia
Newtons first law of Motion defines what property of matter?
Inertia
This is anything that has weight and takes up space
Matter
What is the force that pulls all things together called?
Gravity
What would hurricanes, tornadoes, waterfalls, and earthquakes be considered?
Natural Forces
The amount of matter (stuff) in an object is called?
Mass
F= m x a
What does that stand for and which of Newtons Laws is it?
Force equals mass times acceleration
Newton's second law
In outer space what property of matter is affected and why?
An objects weight due to less gravity.
What is a force that relates to the amount of force put on a given surface area called?
Pressure

an equal an opposite reaction.
Newtons 3rd Law
Who was the scientist that discovered that all things fall at the same speed?
Galileo
What is a force that continually pulls a spinning object towards its center called?
Centripetal Force
When talking about friction created by a substance like air or water, what would the air and water be considered?
A Fluid
The ratio of mass to volume, showing how tightly packed the matter is inside an object.
Density
The Law of Universal Gravitation: Who discovered that every object with mass attracts every other object. He realized that the exact same force pulling an apple to the ground is what keeps the Moon in orbit around the Earth.

Recite Newtons first law completely from your Clarita's definition
An object at rest and an object in motion will continue in a straight line at the same speed unless an unbalanced force acts upon it.
If we measure the distance an object moves in a certain amount of time, we call it.
Speed
