100
This principle keeps ships afloat
What is Archimede's principle
100
Round pits located on the moon
What are craters
100
This planet has seasons because its axis is tilted (not Earth, the other one)
What is Mars
200
Changes in speed, changes in direction, or both
What are ways that velocity changes
200
It depends on the types of surface and how how they push together
What is the strength friction depends upon
200
This law states that if one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction of the first object

400
The energy that an object has due its motion
What is kinetic energy
400
This principle keeps airplanes aloft and explains fluid motion
What is Bernoulli's principle
400
A system where the Earth and other planets revolve around the sun
What is a heliocentric system
400
This planet gets directly between the moon and the sun and causes a lunar eclipse

500
This is calculated using distance over time
What is speed
500
Stored energy that results from the position or shape of an object
What is potential energy
500
