Final answer:
Energy is everywhere and is used in various forms, including food, gasoline, and electricity. To give energy to a table tennis ball, one could hit it with a paddle, transferring kinetic energy to the ball and causing it to move.
Step-by-step explanation:
Energy can be found in various forms and is utilized in many different situations. In the example of giving energy to a table tennis ball, one could simply hit the ball with a paddle. The action of hitting the ball with the paddle transfers kinetic energy to the ball, making it move or bounce. This energy transfer is an example of work being done, where energy is used to move an object.
Beyond this, energy is everywhere around us. It's in the food we eat, which our body converts into the energy it needs to move and grow. It's in the gasoline that powers our vehicles, and the electricity that lights our homes - often produced by chemical reactions such as the burning of coal. The sun provides us with solar energy, which is essential to life on Earth and drives the planet's climate and weather systems.
