Most of the forces currently known to man have their opposites. Magnetism for example will have a North Pole acting opposite to that of a South Pole. For this reason I began to think of a possible opposite to the force of gravity. Although gravity is not very well understood today, it is widely accepted that mass causes gravity and creates the force that pulls two objects together. This type of force is often modeled as a large mass creating a dip in the fabric of space-time causing other object
Based on what we have just learned about torque and rotational motion, should this be possible? I understand the fact that the two objects, equal in weight, would not twist the system around the toothpick, thus maintaining the rotational static equilibrium in this direction, but it is the other direction that astounds me. The fork and spoon are hanging out away from the glass and i would thus expect it necessary for a countering force to be applied on the opposite side of the pivot. When all mas
Currently in AP Physics C, our class is partaking in a unit of independent study for impulse and momentum. Along with the practice multiple choice and short response questions we had been assigned,i decided to used youtube videos to provide a better understanding of the law of conservation of momentum and how this affects real world collisions.
Among many videos of car crashes, billiard shots, and even slaps in the face, this video seemed to be the most unique due to its incorporation o
