What are the two factors (variables) used to calculate speed?
What are distance and time?
100
What type of forces cause an object to start moving, balanced or unbalanced?
What are unbalanced forces?
100
What is an object that appears to stay in place that helps you detect motion?
What is reference point
100
What is Newton's Second Law?
What is the bigger the object, the more force it takes to move it.
100
What is Newton's Third Law?
What is for every action, there is an equal and opposite reaction.
200
What causes changes in speed, direction or both? balanced or unbalanced forces?
What are unbalanced forces?
200
What is a decrease in acceleration called?
What is deceleration
200
What color are the hottest stars?
What is blue?
200
What color are the coolest stars?

300
What is the net force for balanced forces? (I am looking for a number)
What is 0 Newtons
300
What is Newton's First Law of Motion?
What is an object that is at rest stays at rest, an object in motion stays in motion unless acted upon by an unbalanced force.
300
What is the name of the galaxy that our solar system is in?
What is the Milky Way Galaxy?
300
How do astronomers classify galaxies?
What is by shape?
400
How do you calculate density?
What is Density = mass/volume
400
What is the force that opposes motion between two surfaces?
What is friction
400
Why does a ship float?
What is it's hollow shape allows for more air, and air is less dense than water.

How do you calculate the volume of an irregular object?
What is volume by displacement?
500
What is an object's change in position relative to a reference point?
What is motion?
500
What does the color of a star depend on?
What is it's color
500
What type of galaxy is the Milky Way?
What is technically it is a barred-spiral but for this test, the answer is spiral.

What is inertia?
