of an object
EX.) a softball
its for a science fair project and i dont know how to figure the mass of a softball, baseball, golf ball, bouncy ball, and so on...
and my thing is: "how does the mass of a ball affect the distance of the ball"
does that make sense?

The Weight of an object is a force
To get the mass of an object for which you know the weight, you just divide the weight by the acceleration of gravity.

so W = m x a

In English System units, if an object weighs 1 pound, then the mass is 1lbf/32.174 = 0.0311lbm

The mass of a body remains the same no matter where that body is located in the universe.

We don't measure mass directly; there is no "massometer." But we do have scales, which measure weight, which is directly proportional to mass. (Hyper-technically speaking, mass is a property of matter equal to its resistance to a change in speed or direction of travel.) The mass of an object is the same everywhere in the universe. Its weight, however, changes depending upon its location: a bowling ball has greater weight on the surface of the Earth than it does on the moon.

Great confusion arises when people interchange units of weight with units of mass. Scientists, particularly physicists, are very careful about not using the terms interchangeably, but regular folks have no choice if they want to get along in the world with other people. For example, when you weigh a regulation bowling ball used by the pros, the scale will tell you it "weighs" 7.27 kilograms, even though the kilogram is, technically speaking, a unit of mass, not weight.
