Here you will construct energy diagrams for a toy car and learn how these diagrams can be useful. This technique will prepare you for similar uses of energy diagrams in quantum physics.  \nIn general terms physics can be divided into two broad categories-classical physics and modern physics. When we use modern physics to explain a phenomenon, we are using concepts that trace their origin to the quantum revolution that began in the early part of the 20th century. Classical physics is everything else. These two branches of physics share many concepts such as energy, momentum, forces, and conservation laws. They differ fundamentally in the concepts and models, which are used to describe the very small.  \nTo gain understanding of the processes taking place at atomic and subatomic levels, you need the help of quantum mechanics. The objective of the Visual Quantum Mechanics units is to introduce you to some aspects of this relatively new way of thinking and, thus, to learn how we know about very small objects such as atoms and molecules.  \nIn quantum mechanics the concept of energy is frequently used to help us describe events and motion. Instead of describing changes in motion in terms of forces and accelerations, we use changes in energy. A convenient way to describe changes in energy is to sketch a graph of the value of an object’s energy at various locations. When we create such a graph for energy, we call it an energy diagram.  \nUsing energy to describe motion is somewhat different from the typical approach. However, it is a very powerful technique that can be used for both small and large objects.  \nTo prepare you for learning about atoms and other small objects you will first describe the motion of a toy car using potential energy diagrams. You will see that you will be able to describe the motion of a moving object without actually seeing that object or its motion. All you need to know is the energy.  \n1A-1  \nAn example of a potential energy diagram is shown in Figure 1-1. On the horizontal axis is the location of the car while the vertical axis shows the value of the potential energy at each location. It shows us how the potential energy changes along the path of the car. The potential energy is highest for locations between 0 and 0.1 meters, is 0.1 joules, and rises to an intermediate value for 0.2 to 0.3 meters. We shall see we can learn a lot about the car’s motion from this diagram.  \n0.00 0.05 0.10 0.15 0.20 0.25 0.30  \nLocation (meters)  \nFigure 1-1: A potential energy diagram for a toy car .  \nThe potential energy varies with the location of the object. This energy change can arise from a variety of interactions including elastic, gravitational, chemical, etc. In this unit, the potentials are generated with the help of magnets. However, the interactions between atoms and nuclei are of different origin. Therefore, the comparison with the atom that you will attempt later on will only be concerned with the shape of the potential energy curve, not with the origin of the interactions.  \nIn these four activities you will arrange magnets along a track and observe the interaction between these magnets and a magnet on the car. By changing configurations ofthe magnets along the track you will obtain potential energy diagrams of various shapes. In this activity you will arrange the magnets in attractive mode.  \nThe friction between the wheels of the car and the track is relatively high. If we were to account for that friction, it would have made the energy diagrams complicated. However, for the purposes ofour qualitative analysis we will try to think about what would have happened if the friction acting on the car were very small.  \nIn this activity we will frequently make approximate sketches of the energy of the toy car.
