This week we mostly discussed how energy is transferred to different objects. We used a demonstration with a bowling ball and a string to show how energy dissapates. Also, this weeks lab was testing to get measurements on a car that bounced off of walls on each side of the track.
The demonstration showed that energy will constantly leave an object if no other force is acting on it. If you swing a bowling ball by a string and release it from a certain point, it will not return to that point because some of the energy had dissipated from it and it is not swing with as much force as it originally had.
We also learned that you can feel, hear and even see energy dissapating into another object. Like if you get hit with a ball, the bruise that you get is a result of the energy from the ball affecting the nerves in your arm. You can see energy dissipating by seeing if another object moves after being hit by something else. Hearing energy dissipate is like when you shoot a basketball and it makes a clanking sound off of the rim because you missed.
This lab that we did this week involved us measuring the distance traveled by a car on a track that bounced off of walls. We had to measure the distance within two seconds. Then we had to make LOL graphs that showed where all the energy was at the time of each of the 5 trials. This lab helped me get that the more potential you put into something, the farther it will go.
I believe that I get everything thats being taught this week. I found it really interesting that dissipated energy came in the form of sound. Actually, this whole energy unit that we're doing now is pretty interesting.
