Unit 1
He discovered a mathematical relationship between gravitational force and the motion of the planets.
Who is Issac Newton?
When you are headed back home, your position on a position-time graph does this.
What is decreases?
Newton's Third Law states for every action, there is this.
What is an equal and opposite reaction?
Created when H2O freezes, it is nice for a hot day or refreshing in a glass with soda - but it's still water.
What is ice?
This is the smallest basic unit of matter.
What is an atom?
He determined how much a spring stretches based on the amount of force put on the spring.
Who is Robert Hooke?
This is force applied to an object by another object.
What is applied force?
This is one possible result of magnetism, if you're feeling pulled in.
What is attraction?
This is the degree of consistency measured by the quantity of mass per unit volume.
What is density?
These are on the left side of the periodic table.
What are metals?
He experimented with balls on ramps to understand motion.
Who is Galileo Galilei?
This field force could have a powerful "pull" on you...if you're dressed in a metal suit.
What is magnetic force?
This is the energy that an object has because of its motion.
What is kinetic energy?
This is the only state of matter with a definite volume but no fixed shape.
What is a liquid?
A molecule made of atoms from different elements.
What is a compound?
Your position will show this when you start to run.
What is acceleration?
What is in motion?
An electromagnetic wave of a frequency between about 10^4 and 10^11 or 10^12 Hz that are used for long-distance communication.
What are radio waves?
This is the unwanted oxidation of metals which results in metal oxides.
What is corrosion?
This mixture has the same uniform appearance and composition throughout and are often referred to as solutions.
What is a homogeneous mixture?
This type of acceleration can be considered similar to a crossroads.
What is changing direction?
Newton's second law states that this happens when a force acts on an object.
What is acceleration?
This can be a different result of magnetism, if you're feeling pushed to answer.
What is to repel?
These are easy to compress, expand to fill their containers, and occupy far more space than the liquids or solids from which they form.
What are gasses?
A mixture that consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.
What is a heterogeneous mixture?
