Use at least two to three completed content related sentences to explain why physics is considered the basic science. Provide at least one example to explain how physics relates to other sciences.
You do work on something when you lift if against gravity. Explain how work relates to gravitational potential energy using at least two complete content related sentences. If the lifted object is released, describe the change in energy. Be sure to define all terms used in both questions.In terms of momentum change, explain why it is best to "give" when catching a baseball. Provide at least TWO other examples of situations in which you want "give". A boy fires a table tennis launcher. Briefly describe the forces and impulses on the launcher and the ball. Explain which has momentum. Explain which is moving faster. Be sure to use at least 3 to 4 complete content related sentences. Write 4 to 5 sentences about what Chapter 1 says about the early scientists from Aristotle to Galileo thought about the nature of motion. (Hint: Need to include Aristotle, Galileo, and Copernicus. Suppose you are on an airplane moving at high speed. If you flip a coin straight up it will land in your lap rather than a great distance behind you. Explain why this is true and include any laws that help prove your point. Your answer should be at least 3 to 4 complete content related sentences.
