We now have a feel for energy and for conversion of one form of energy to another (for example from chemical energy to heat). Work is the energy transferred from an agent applying a force to an object or into heat, and the net work done on an object is the total change of kinetic energy.

WebNo, because we know now that during the horizontal motion, gravity's not doing any work. So this displacement doesn't come into the picture. During the vertical motion gravity is doing work. Gravity is pulling and make it displace, so this matters. Again, during the horizontal motion, that displacement doesn't matter.
