Gravity Flashcards
1
Q
Gravitational Force Equation
A
Fg = Gm1m2/r^2, G = 6.67e-11
2
Q
Total energy and angular momentum of a satellite
A
Both total energy and angular momentum are conserved. Therefore, as the satellite gets closer to the planet (smaller r), it speeds up (larger v).
3
Q
The gravitational acceleration g of earth depends ONLY on…?
A
the mass of the Earth and the distance the satellite is from the center of the planet, NOT on the mass of the satellite.
