What is the Law of Conservation of Energy?
~ The Law of Conservation of Energy is a scientific principle that states that the total amount of energy in a closed system is constant, meaning that energy cannot be created or destroyed.
Based on the Law of Conservation of Energy, how would a person on a skateboard achieve forward motion?
~ According to the Law of Conservation of Energy, the rider uses his or her muscles to convert chemical energy into kinetic energy. The kinetic energy from his or her body is then transferred to the skateboard, where the accumulated kinetic energy results in forward motion.
What happens when an object in motion encounters the force of friction?
~ When an object in motion encounters the force of friction, the object's kinetic energy is converted into other forms of energy, mostly heat. When all of the object's kinetic energy is converted, the object comes to a stop.
