That the forces sum to a non-zero resultant.
Such a figure is called a square. Actually only one right angle is enough to force the the other angles to be right, and if three sides are equal, that forces all sides in such a figure to be equal. Exercise: Prove that any 4-sided figure( called a quadrilateral in math books) with three equal sides and one right angle is a square.
The applied force will depend on the required force, and the angle to the ramp (or the horizontal) at which the force is applied.
There are many practical applications. here's one: On my farm, I often need to uproot trees and stumps. If I hook a chain to my tractor and a tree/stump and try to drive away, the force holding the tree in place overcomes the force holding my tractor tires to the ground, and the tires slip. So I hook the chain to the tree I want to remove, and (tautly) to a larger one nearby instead of to my tractor. I then hook a second chain to the middle of that chain, and the other end of the second chain to the tractor. I then drive the tractor away perpendicularly to the first chain. I am in essence adding (a portion of) the force holding the larger tree in place, to the force being applied to the tree I want to yank free. Put another way, I am creating more pulling force on the stump to be yanked, with the same motive force limit on the tractor (the point at which the tractor slips.) Do NOT try this without experience, because of the risk of chain snapping and taking your fool head off. I haven't bothered to describe my safety procedures ( among other things I tie the chain off at several crucial points so that if it snaps it can't reach me or my equipment) because those procedures aren't pertinent to the question.

It can slide if there is enough force to overcome static friction. Similarly, it can roll if the force is great enough to impart a sufficiently large turning moment (and maintain it).

The term n-gon, where n is the number of the polygon's sides, also it could be used to name a polygon. For example, a polygon with 15 sides is a 15- gon.
All the concurrent forces acting at a point can be represented by a polygon's sides closing with the resultant force equal in magnitude and opposite in direction.
The direction of the arrow indicates the direction of the resultant force. The length of the arrow indicates the amount of the force. Resultant means the net result of two or more forces.
No force is necessary to keep a moving object in motion. But if you want it tofollow a curve, such as for example a closed orbit, then that takes force. Theforce that keeps Neptune in its closed orbit is the same force that keeps everyplanet, moon, comet, and asteroid in its own closed orbit around its own centralbody. It's the force of gravity.
mechanical advantage
A force acting on it.
That's the velocity at which the force of air resistance is equal to the force of gravity.
Acceleration = force in newtons divided by mass in kilograms
Same as on Earth. In both cases, you can use the law of gravitation to figure out with how much force an object gets attracted.Same as on Earth.
