Problem: Weight is actually just a one-word nickname for the force of gravity acting on an object. Many physics educators don't like the term since it can confuse in many students–but the term is very common, and you are likely to encounter it in your physics study materials including, probably, your textbook.What is the correct formula for the weight w of an object? Assume that the object's mass is m, the magnitude of its acceleration is a, and the local acceleration due to gravity is g.Select the best answer from the choices provided.A. w = m(g•A)B. w = maC. m(g+a)D. w = mE. w = mg
