Energy is the ability to do work or cause change. It comes in various forms, such as kinetic energy, which is the energy of moving objects, and potential energy, which is stored energy based on an object's position. For example, a stretched rubber band has potential energy that can be released when it snaps back, turning into kinetic energy as it moves. Force, on the other hand, is a push or pull that can change an object's motion. It is measured in newtons and can cause an object to start moving, stop, or change direction. For instance, when you kick a soccer ball, the force of your foot propels the ball forward, demonstrating the relationship between force and motion.
