What is the difference between weight and mass?
Technically, mass is the amount of matter in an object (measured in kg), while weight is the force of gravity acting on that mass (measured in Newtons). In everyday use, 'weight' is used interchangeably with mass. On the Moon, your mass is the same as on Earth, but your weight is about 1/6 as much.
