... force can be determined from a graph of applied force versus displacement. The area under a force–displacement graph for an ideal spring has the shape of a triangle. The area of this triangle equals the work done on the spring by the applied force. This applied force is equal but opposite to the spr ...

... Consider now the pendulum (see the figure). We will use again the second Newton’s law to find the equation of motion. Let the length of the pendulum be l and the mass be m. Now we need to consider the projections of the forces on two axes. One is along the pendulum itself, and there the force of ten ...
