As I woke up today I was wishing for just a two hour delay because I knew if we had one I would not miss my favorite class, Physics. As I walked towards Mr. Manning's room I was in a state of confusion since the day before we did not have school which was a surprise. I entered the room to find everyone already in their seats because which was not normal because I was usually the first one in, but because of the delay we started with homeroom. I picked up the paper we needed for class and sat in my seat. As I sat down I looked at the paper I just picked up and it was labled, The Manning-Made Pile Driver Lab: Physics 1. I was really looking forward to this because anything to do with Manning is always fun and exciting. To my disappointment since we had a shortened period we did not get to that paper. Instead we read over page 13 in our binders and answered questions which included:


 * Are Height and Displacement the same thing? || Yes they are because they both have a starting position and a end position. Starting Height=Starting position and same with end height=end position. ||
 * Does weight equal a lifting force? || Because it moves at constant speed ||
 * Why is the triangle h usually the same as h? || Because the starting height is usually at zero. ||
 * What is changed to lift something? || Potential energy is changed. ||
 * triangle X= u*t || u=triangle X/t ||
 * How do you simplify it? || [[file:untitled..bmp]] ||
 * What is changed to move something horizontally? || kinetic energy ||
