Unit 1
The equation of speed
Speed = Distance/Time
(v=d/t)
The difference between contact force and field force
Contact force = acts through touch
Field force = acts through a distance
What force says that every action force has an opposite and equal reaction force
Newtons third law of motion
Three main types of rock
igneous, sedimentary, metamorphic
what are the coldest and hottest planets
Coldest = Neptune
Hottest = Venus
The equation of velocity
velocity = displacement/time
What is the force that resists motion
Friction
What is the difference between potential and kinetic energy
potential = not yet in motion/stopped
kinetic = is in motion
What are all the gas giants
Jupiter, Saturn, Uranus, Neptune
what are seasons
The year divided into four, winter, spring, summer, and fall. These are all caused by the sun and the earths positions.
The equation of acceleration
acceleration = velocity/time
What is inertia
If an object is in motion it will stay in motion and if an object is stopped it will stay stopped. Both of these occur unless a force acts upon it
A wave changing its direction when moving from one medium to another, a wave hits glass, water, etc. and bounces back.
what is a refraction and reflection
What makes a planet a planet
revolves around the sun, has enough mass to be spherical and to clear everything around it
What are all the different moon phases
