gravity
RADAR determines the distance and direction to anything that reflectsradio waves ... usually material objects, but it responds to atmosphericphenomena too.
There is a force of gravity in each direction between every two objects that have mass. The forces attract the two objects toward each other. All the time. Doesn't matter what the objects are, or how far apart they are. Doesn't matter whether they're moving or still.
Objects comprise of charges.Opposite charges attract each other.
Mass is the amount of material in an object. The more material in an object, the more material you have to get moving before the object itself moves. Have a friend pitch you one baseball. You will notice the recoil of the bat. Ducktape 2 or 3 baseballs togeter and have your friend pitch them to you. The recoil will increase significantly because you have to change the direction of more objects. The more objects, the more mass.
