Which takes more fuel, a voyage from earth to moon or from moon to earth? Explain.
Imagine that the sun somehow became twice as massive as it is now. What effect would this have on your weight on earth? Explain.
If a projectile is fired straight up from the earth's surface, what would happen if the total mechanical energy (kinetic plus potential) is
a. less than zero?
b. greater than zero?
In each case, ignore air resistance and gravitational effects of the sun, the moon, and other planets.
thanks in advance guys
