- 1In what way does the force of gravity between Do two objects depend on their masses?When mass increases, so do the force of gravity. When mass decreases, so does the force of gravity.
- 2How does the force of gravity depend on the distance between two objects?An increase in distance will reduce the force of gravity. Distance and gravitational force have an inverse square relationship.
- 3How does the force of gravity between two objects change when the distance between them is doubled?The force decreases by a factor of 4.
- 4How does the intensity of light, radiation, and sound change when a point source is twice as far away?They all follow in inverse square law, so all are 1/4th as large.
- 5Do you escape from Earth’s gravity if you’re above the atmosphere? By being on the moon?Still some attraction to Earth for both.
- 6At what distance away from Earth is Earth’s gravitational force on you zero?Technically, no matter where you are there is always SOME attraction to Earth. But it might be very, very, VERY small.
- 7If the moon were twice as massive, would the attractive force of Earth on the moon be twice as large?Yes
- 8By what factor would your weight change if the Earth’s diameter were doubled and its mass was also doubled?1/2 as much
- 9Find the change in the force of gravity between two objects when both masses are doubled and the distance between them is also doubled.unchanged
- 10You stood atop a ladder that was so tall that you doubled your distance from Earth’s center. Your new weight would be __________ as your normal weight.1/4th as much
- 11Consider a pair of planets that both somehow double in mass while keeping their same distance apart. By what factor does the force of gravity change between them?the force would quadruple
- 12By what factor does the force of gravity between two planets change when masses remain the same but the distance between them is increased by four?the force would be 1/16 th
