Applied Concepts Flashcards
What is true about multiple objects shot from the surface of the earth (or “into orbit”)
They all have the same acceleration towards the center of the earth
What is escape velocity?
The speed required for an object to break from orbit/atmosphere
What is true about all orbits in our solar system?
They are elliptical (circles = special case of an elipse)
when does an object have parabolic/hyperbolic “orbit” (trajectory)
When not bound gravitationally to an ongoing orbit (e.g. a comet shooting momentarily from outside the solar system and being redirected by the gravity of the sun)
How does elliptical orbit differ for two objects orbiting around a common focus?
Low mass object = Larger elliptical, high mass object = smaller (tighter) eliptical
What is the temperature of a gas?
Kinetic energy per molecule
What is the (temperature) of a solid
Vibrational energy (per molecule)
What does temperature measure?
The average motional energy
How does heat flow?
From higher temperature object to lower temperature object
