- Rotation
- spinning motion of a body(planet) on its axis
- counter clockwise
- from teh north pole of a planet retrograde rotation
- revolution
- the motion of a body(planet) as it orbits another body in space.
- i can define vacum and free fall and describe how they are related.
- free fall- when gravity is pulling an object down and no other force is acting on it. vacum- an area or place with no air.
- i can list 3 parts of projectile motion.
- horizontal velocity, vertical velocity, actual motion from curved path.
- i can list the distance of one astronomical unite (AV) and describe what that distance represents.
- AV= 150 millinon km average distance to sun.
- list the order of the nine planets in our solar system.
- mercury, venus, earth, mars, jupiter, saturn, uranus, neptune, pluto.
- define escape velocity
- how fast you have to go to get out of a planets gravitational pull.
- what is the escape velocity for planet earth.
- 11.2 km/s
- if you increase the mass of a planet what happens to the gravity of that planet
- the gravity increases.
- what does this quote mean to you: a scientist doesnt read about there discovery before they make it.
- your discoveries arn't going to be in a text book. you have to think outside the box to make a great discoverie.
- where is the astroid belt
- in between mars and jupiter
- what is a comit made of
- dirty snowball, big pile fo rocky material coated in different types of ice.
- how does teh sun produce light and heat
- the elements in the sun creat light and heat.
- what is the difference between equinoxes and solstices?
- solstice= either really close to the sun or really far away from the sun. equinox= 12 hrs of day and 12hrs of night. reasons for the seasons= tilt of the earth in relation to the sun.
- what is balie's tamagochies name?
- beth!!!
- what is the largest and smallest planet in our solar system.
- largest is jupiter and smallest is pluto.
- what galaxy is our solar system in.
- the milky way!
- how long is one rotation of the earth?
- 1 day
- why does the dionostic matter of pluto effect the maticulate mass of saturn?
- nobody knows!
- what elements give mars its redish brown color
- iron + oxygen + rust.
- how long does it take light to get from teh earth to the sun.
- 500 seconds, 8.3 minutes.
- why is balie so beautious
- nobody knows shes just so wonderously glorious.
- how long is one revolution of the earth
- 1 year.
