Chart regarding the weight and mass of an object
Explanation:
Mass and weight are often used interchangeably in everyday conversation. For example, our medical records often show our weight in kilograms but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of Earth on an object. It depends on the distance from the center of Earth. Unlike weight, mass does not vary with location. The mass of an object is the same on Earth, in orbit, or on the surface of the Moon.
Units of Force
The equation
F net = m a is used to define net force in terms of mass, length, and time. As explained earlier, the SI unit of force is the newton. Since
F net = m a ,
1 N = 1 kg ⋅ m/s 2 .
Although almost the entire world uses the newton for the unit of force, in the United States, the most familiar unit of force is the pound (lb), where 1 N = 0.225 lb. Thus, a 225-lb person weighs 1000 N.
