A locomotive is pulling 16 freight cars, each of which is loaded with the same amount of weight. The mass of each freight car (with its load) is 37,000 kg. If the train is accelerating at 0.

What is the special feature of the upper mantle?

What is the difference between weight and mass? mass and weight are both intrinsic properties of an object. if you multiply the mass of an object by the acceleration due to gravity, you will obtain the object's weight.
