Centre of Gravity
Pull the Doll to one side using the rope provided and Observe.
What did you observe?
The centre of gravity (COG) is a hypothetical point around which the force of gravity appears to act. In an upright Doll the centre of gravity (CG) in the weighted bottom is above the point of support. Tipping the Doll shifts the centre of gravity away from above the point of support. When the Doll is released, the force of gravity acts on the centre of gravity and produces a torque that makes the toy roll from the point of support. When it reaches the upright position, its inertia makes it roll too far. It rolls back and forth and finally comes to rest standing upright.
