A moon is located at  1 unit out from the planet it orbits. If that moon was orbiting at 2 units out from the planet, how much would the gravitational force on the moon be compared to its distance at 1 unit?

• 1/4
• 1/6
• 2x as much
• 4 times as much

Ocean tides occur mainly because 

• water normally runs to the side of Earth away from the sun
• of the gravitational pull of the sun on Earth
• of different gravitational pulls of the moon on opposite sides of Earth
• as Earth rotates it leaves the ocean water somewhat behind it

A planet moves fastest during its orbit around the Sun at the when 

• it is closest to the sun and gravity has a stronger pull
• it is farthest from the sun and gravity has a stronger pull
• it is closest to the sun and gravity has a weak pull
• it is farthest from the sun and gravity has a weak pull

• 360 lbs
• 0- you are weightless in space
• 18 lbs
