First order of business: Read **Total Mechanical Energy Lab: Physics 1** After about five minutes, Manning requests that we clear our desks in preparation for... something. Graded daily question. To make sure we were actually reading the lab, as I assume many weren't, we were asked a few questions that are as follows:

1. Q: What is the question that the lab aims to answer? A: "A steel cart is given a certain amount of Potential Energy when it is lifted to the top of a ramp. As the cart is released from rest and rolls down the ramp, it loses Potential Energy and gains Kinetic Energy. How will its Total Mechanical Energy at the bottom of the ramp compare to its Total Mechanical Energy at the top?"

2. Q: What bits of data must be measure for this lab? A: Change in height, Change in potential energy, Displacement, Time, Acceleration, Final Velocity

Extra Credit. Q: There was an error made on the lab... what was it? A:On page two, the unit of measure for Kinetic Energy should be Joules and not Meters.

Unknown to Mr. Manning, the lab was on the smartboard screen. Taylor, however, always screwing things up, squawked aloud, "Isn't it like, right up there?" Dumb.

For the remainder of the class period, we worked through the lab.
