Wednesday's Class

Today in class we started to take notes on inertia. We did an experiment where we put a block of dry ice on a level ramp. When the ramp was perfectly level, the dry ice did not move. We then set up a motion sensor at one end of the ramp, and pushed the dry ice towards it. The block of dry ice moved at a constant velocity towards the motion sensor and had an acceleration of 0. We began to talk about forces, and what forces were acting on the block of ice. We determined that the gravitational of the earth was acting on the block of ice, as was the force of the hand that was pushing against the ice. For the second half of class, we worked on our texting projects.
