100
This includes speed and direction
What is an object's velocity?
100
An object moving at constant speed is experiencing ________________ forces.
What is balanced?
100
This is the amount of matter in an object.
What is mass?
100
This subatomic particle has a negative charge and orbits around the nucleus of an atom.
What is an electron?
100
This planet is closest to the sun.
What is mercury?
200
This is the equation for calculating speed.
What is Speed = Distance/ Time?
200
This is another word for the strength of a force.
What is magnitude?
200
This is the amount of space something takes up.
What is volume?
200
These two subatomic particles are found in the central part of the atom, also known as the nucleus.
What are protons and neutrons?
200
This unit of measurement is used to measure distances with our solar system.

300
This is the average speed of a car that travelled 210 km in 3 hr.
What is 70 km/hr?
300
This is the definition of a force.

300
This is the density of an object with a mass of 25g and a volume of 5 cm^3.
What is 5g/cm^3?
300
The vertical columns in the periodic table are called this.
What are groups?
300
Distances between stars and galaxies are measured with this unit of measurement.
What are light years?
400
A change in velocity.
What is acceleration?
400
This is the force of attraction between two objects due to their masses.
What is gravity?
400
This is the equation for calculating density.
What is Density= Mass / Volume?
400
These elements are good conductors of heat and electricity.
What are metals?
400
This is the only source of light in our solar system.
What is the sun?
500
The slope of a distance vs. time graph represents this.
What is speed?
500
This is a force that occurs when two surfaces rub together.
What is friction?
500
This is the density of water.
What is 1 g/cm^3?
500
These are formed when two or more elements combine chemically.
What are compounds?
500
These are the three most common shapes of galaxies.
What are spiral, elliptical, and irregular?
