The Law of Conservation of Energy states that energy cannot be created or destroyed but can be changed from one form to another. When you release a toy car, you notice that it slows down and eventually comes to a stop but the wheels are slightly warm to the touch. Explain how the law of conservation of energy is obeyed in this scenario.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
