Hello, everyone! It's been quite a whole since I posted, huh? Anyways, today I'm posting about forces. A Force is anything that causes an object to undergo a change in speed, direction, or shape. For example, the stapler in this picture is actually being acted upon by different forces. The reason it isn't moving everywhere is because the forces are balanced. One such force is weight, which can be seen by the equation Fnet=ma. Reacting against weight is the "normal force", which is always the same as weight. So, since the two forces are balanced, the stapler is at rest.
