Oh, dude, you're hitting me with the heavy physics stuff now. Mass times distance? That's just the mathematical way of saying how much stuff you're moving and how far you're moving it. It's like, if you're carrying a sack of potatoes, the total weight you're lugging around depends on how many potatoes are in there and how far you have to schlep them.
four times as great
Here are two equations that might be useful.Newton's Second Law: force = mass x accelerationDefinition of work: work = force x distance
Acceleration. This is described by Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. This relationship is represented by the equation F = ma.
The mass of the first object; the mass of the second object; the distance between them.The mass of the first object; the mass of the second object; the distance between them.The mass of the first object; the mass of the second object; the distance between them.The mass of the first object; the mass of the second object; the distance between them.
Mass: kilogram Volume: cubic meter Distance/length: meter
Momentum. Distance divided by time is speed. Mass times speed is momentum.
The distance from the center of mass to Earth, times the mass of the Earth, must be equal to the distance of the center of mass to the Moon, times the mass of the Moon. (For more than 2 objects, the calculation is somewhat more complicated - reading about "center of mass" can give you an idea.)The distance from the center of mass to Earth, times the mass of the Earth, must be equal to the distance of the center of mass to the Moon, times the mass of the Moon.

(mass X distance)/(time X time), or mass times acceleration
Speed times time equals distance
The gravity of a planet is directly proportional to its mass, and inversely proportional to the square of the distance from the center of mass. For the gravity on the surface of the planet, the distance is just the planet's radius. Thus, if a planet has three times the mass, it has three times the gravity. If you are three times as far away, the gravity decreases by a factor of nine.
Force of gravity equals mass of planet times mass of other times the constant (G) that makes the units work all divided by the distance from one to the other AND the other to one (turns out to be distance squared). F=GxM1xM2/(DxD)
