... If you and a friend both push on the same side of the dresser, the forces that you both exert are in the same direction. When the forces acting on an object are in the same direction, they add together, as shown in Figure 4, to form the net force. When you both push on the dresser in the same direct ...

... m (E − V(x )) One may wonder how this formula for energy arose from Newton’s equation. Let us consider one degree of freedom. We wish to integrate m ẍ = − dV dx with respect to time in order to solve the equation of motion. To do so we notice that ẋ is an integrating factor. For, multiplying the e ...
