ILS 2012 gravity
Question | Answer |
---|---|
Gravity | not the same everywhere, depends on mass and distance, mass directly, distance inversely |
Weightless | gravity is still present |
Mass | amount of matter in an object |
Volume | amount of space an object takes up |
Eccentricity | length of an ellipse |
Force/Weight | SI unit is Newtons, mass times gravity, weight decreases as you get farther away from Earth |
Inertia | property of matter that resists change in motion, move in straight lines |
Ellipse | shape of a planet’s orbit |
Orbit | caused by gravity and inertia |
Sun | orbited by planets and comets, formed by most of the mass from the solar nebula |
Tides | caused by gravity from sun and moon |
Jupiter | largest diameter |
Planets and characteristics (project cards) | temperature, diameter, moons, tilt of axis, composition, revolution |
Heliocentric/ Geocentric | Sun centered, Earth centered |
