Mousetrap

 

     Before I played with both ping pong ball and mouse trap. I played with the mouse trap. I got everything set (put the hold-down bar on the small button.) when I tried to put it on the floor it suddenly starts working and clipped on my finger. it's hurt for a long time but I felt how much power this small trap has.

     The extruding of the spring gives the potential energy to the equipment. Potential energy is the energy that has been stored but not be used. It converts to the kinetic energy when the  equipment is working. Kinetic energy is the energy of motion.

     The way to let the ping Pong ball go further, is get the lever arm which is hammer longer and let the ball get out of the equipment in 45 angles.

      This is a good experiment about newton's first law.

How Challeng Hon Physics is

     Honer physics is not a kind of course that you can still get good grades without preparing before every class and do lots of practice after that. That's means you have to do lots of work to get a good grade. And it's only based on you understand the topic first and know what formulas are standing for. 

     As a foreigner, understanding English is hard for me. Understanding the physics is much more difficult for me. I have to know how the stuff move from which way to which way, it's acceleration or decoration. I even have to know if the ball has a Vo from the words is dropped or throw. 

     Even though the class is challenging but it doesn't mean the class is unavoidable. Being positive and try my best can help me to reach higher and higher.
