Gravity

Question 1

Gravitational Force Equation

Answer 1

Fg = Gm1m2/r^2, G = 6.67e-11

Question 2

Total energy and angular momentum of a satellite

Answer 2

Both total energy and angular momentum are conserved. Therefore, as the satellite gets closer to the planet (smaller r), it speeds up (larger v).

Question 3

The gravitational acceleration g of earth depends ONLY on…?

Answer 3

the mass of the Earth and the distance the satellite is from the center of the planet, NOT on the mass of the satellite.
