More fun with Energy!

Today we began class by continuing the bungee lab! Since our group finished it on Friday we decided to start working on our bottle rocket. My partner and I finished cutting the bottles and making the parachute! Soon after everyone finished their lab Mr. Blake explained more about energy! This was shown by using the bowling ball, he explained that the ball starts out with no energy then gains potential energy. The point at which that ball is released from is the point where the ball has the most energy. Then on the balls way down it loses potential energy and gains kinetic energy. We did more practice of work and power by doing a lab. The lab was having two people run up and down the stairs at the fastest they could! Then we calculated the amount of work and power they had using their mass and time.

After we finished the lab we got to begin day one of launching. This launch was just meant to get us comfortable with the pumps and all. The first launch our table did didn't work well because there wasn’t enough pressure so it just flew directly sideways almost taking out 3 people! Haha but soon after we got the hang of it! I can't wait until we get to test out the real rockets and I hope the rocket eating tree doesn't get my rocket!

 

This is a picture of me and my friend Jamie. This picture kind of relates to the lan we did today. Jamie and I were sprinting as fast as we could to see who got to the dog first. We went the same distance and in the same path BUT since my mass is more than Jamie's I would have done more work because i would need more force to move. If i had a faster time though (even though i think jamie won) there could be a possibility that i had more power too!
