- Title
Physics Activities With Metersticks.
- Authors
HEWITT, PAUL G.
- Abstract
Interestingly, if the clay were located at the middle of the stick, the effects of greater torque and greater rotational inertia would balance each other and both sticks would rotate to the floor together. You can see there are two centers of mass to consider here: one of the lone meterstick, CM[sub stick], and the other of the system of meterstick and clay, CM[sub system]. Clay-stick balance To better understand the CM of the two-tick combination of Figure 6, consider a single horizontal stick with a glob of clay stuck at its 0-cm end (Figure 7). Although greater torque acts on the clay-topped stick than the empty stick, its effect is offset by the greater rotational inertia of the clay-topped stick.
