I walked into the classroom a little disappointed from the Phillies loss the previous night to find Mr.Manning back from his two days off. Class started off by reviewing the daily question and starting the packet called Acceleratin' Experiences. The day before the class received the packet but majority did not understand it. Mr.Manning went through majority of the packet on Friday to make sure every student knew the material. Inside the packet were five different formulas that are needed for this unit. The first two are for uniform acceleration only. The first one is velocity = change in position divided by time. The second formula is velocity = (final position + initial position) divided by two. The third formula is acceleration = (final velocity - initial velocity) divided by two. The forth formula can be used to solve for acceleration, time, and initial velocity. The formula is the change in position = 1/2(acceleration)(time)² + initial velocity (time). The last formula is final velocity² = initial velocity² + 2(accerlation)(change in position). All of these formulas are important to this unit on acceleration. The last thing we learned in this packet is linear motion diagrams. To make a linear motion diagram one must draw a picture of what is moving. Then write above the picture whether it is speeding up, slowing down, or constant. Then under the picture write the velocity (positive or negative) and acceleration (positive or negative). Below is a picture that can be an example of a linear motion diagram. Everyone left class that day with more knowledge of acceleration.
