Review Before Test

Hi everyone. I'm going to be posting the review for tomorrow's test on gravitation and orbits.

REVIEW

Kepler's 3 Laws

For the orbital of planets the Sun is one focus point.

The areas created between 2 equal intervals of the planet's orbit are equal


Kepler's Formula


Newton's law of Universal Gravitation




Gravitational Potential Energy




Escape Velocity & g of a Planet or Sun & Orbital Velocity

Thanks Richard!

Newton's Thought Experiment
To stay in Earth's Orbit the satellite must have a velocity between 8km/s to 11.2km/s

Orbital Period


Microgravity
What is it?
-Environment with very little gravity

How can it be achieved?
-By gaining altitudes rapidly then suddenly decreasing altitude rapidly like during the NASA Microgravity Simulating Planes

Problems of Space Exploration
-Hazards
-Expense

That is all we had for a review. I might add more stuff if I find something but for now I'm getting some rest. I gotta study. Good luck tomorrow and the next scribe will be Francis.
