Explain the steps to calculate final velocity when many masses collide? How to calculate the energy change in the reaction N_2(g) + 3H_2(g) rightarrow 2NH_3(g)? In the context of physics, explain the statement, "The moon is falling." ...
The acceleration due to Earth's gravity has a (roughly) constant value anywhere on the surface and points directly to the center of mass of the planet: g = 9.81 m/s2. Given this constant value, the only things you need to calculate GPE are the mass of the object and the height of ...
