Final answer:
To find the angle at which the seated teddy bear will tip over, one must analyze when its center of gravity exceeds its base of support. The placement of weights, such as in an experiment with pennies on a ruler, helps demonstrate balance and tipping points in static objects.
Step-by-step explanation:
To determine at what angle the seated teddy bear will tip over, one must consider the concept of the tipping point. The tipping point refers to the situation where the center of gravity of an object, such as a toy block with wheels (TBWC), extends beyond its base of support, causing it to topple. This is affected by factors like the angular momentum in the case of rotating wheels or the distribution of mass around the object's pivot point.
For an object at rest, like the seated teddy bear, the tipping occurs when the line of action of the gravitational force falls outside its base of support.
Correspondingly, in the provided TAKE-HOME EXPERIMENT with the ruler and modeling clay, the balance or tipping can be explored by adjusting the distances at which pennies (masses) are placed from the pivot point. The balance point shifts with the placement of weights (pennies), and finding the exact positions for them can illustrate the concept of static equilibrium and tipping points.
