This week we learned about energy. My roommate is shown above, standing on her bed. She is about 62 kilograms, and the bed is about 0.5 meters above the ground. I can determine her gravitational potential energy by using this information. The formula is PEg=mgh, which is mass times gravity times height. Therefore, her potential energy is 62 kg(0.5 meters)(10 m/s2), which comes out to 310 Joules. If she fell to the ground, her potential energy would gradually change to kinetic energy. However, when she stopped at the ground, her potential energy would be 0 J.
that is a great explanation of energy and it is good because it is something that happens to people everyday.
ReplyDeletei like how you applied the lesson to a real life situation problem. It helps people to understand the energy equations a little better.
ReplyDeleteThis was a great example on applying physics energy to your personal life. It was very well thought out and thorough. There was good definitions and it was easy to understand. Especially, the problem solving part! Good job Shelly!
