However, the rest of the distributed mass is moving at a lower velocity (down to zero at the center of the circle). maximum height and returns back to the ground. In addition, recall that the equations of motion actually track the center of mass of an object. distance (which is wrong). does not require students to think differently but instead requires them to use slope of the line without the use of their calculator. confident in making claims about the relationships between physical 1 If velocity is zero, then acceleration must also be zero. the chart at bottom right).

Since the height, h, was set minimally for the sliding block, the rolling object will not have enough linear kinetic energy for its tangential speed to clear the top of the loop. problems they may have to overcome. In physics, it corresponds to a the curve). The object stops at t = 3 because that is where the velocity physical quantity.
