Physics:
Newton’s second Law of motion lab-
We started the class by discussing what would happen, to acceleration, if the mass of an object was changed but the Force was unchanged. We then used a ruler to control Force, and a set of balls (Ping-Pong, base, and wiffle balls). First the mass of the balls was recorded. We bent the ruler to the same degree, to control force, and slapped each ball. We observed the speed by which each ball hit the opposite wall. We compared our notes to see the higher the mass, the slower the motion. We then used a baseball and a ball made of a small amount of paper, to see how Mass affects Force. The larger ball had no problem knocking down a series of dominos, while the smaller ball had real trouble knocking them down, showing the lower the mass the lower the force, when acceleration was constant.
