force and acceleration
... Mass is a measure of the amount of matter in an object. As already mentioned, mass depends on the number and kinds of atoms in the object. Weight, however, depends on gravity. You would weigh less on the Moon, for example, than you do on Earth. Why? The Moon's gravity is weaker than Earth's, so you ...

... Weight is the gravitational force that the Earth exerts on all masses. Close to the Earth, the size of the force on an object can be calculated by multiplying its mass by (the acceleration due to gravity), that is :W = mg, where g =9.8 Newton/kg or m/s2. It also acceptable to approximate this to 10 ...
