Balanced/Unbalanced Forces By Kendall Grube

Forces are acting on everything, everywhere, all the time.

These planes have unbalanced forces working on them. There is thrust, which is moving the plane forward, drag, which is trying to move the plane backward, weight, which is pulling the plane down, and lift, which is pulling the plane up. If all of these forces were equal, the plane would be sitting still, but since the thrust and lift are greater than the drag and weight, the plane moves up forward.
The planes in these pictures are all sitting still. This means that though forces are still acting upon them, the forces are balanced. For example, gravity pulls down on the planes, but the pavement pushes up. This may seem a little strange, but it's why the planes aren't being sucked into the ground.
