Free body diagrams show all the forces acting on an object. For example, a skydiver's weight acts on him by pulling him down towards the ground- air resistance (drag) acts upon him, in the opposite direction to his motion. What do the sizes of the arrows show?
Right? We have these two arrows that point in different directions. So in this problem, what happens is that because forces are vectors, then when a force acts at some angle in two dimensions, we just treat it like any other vectors. And we're just going to decompose it into its x ...
4.1 The Concepts of Force and Mass Arrows are used to represent forces. The length of the arrow is proportional to the magnitude of the force. 15 N 5 N 4.1 The Concepts of Force and Mass Mass is a measure of the amount of “stuff” contained in an object. 4.2 Newton’s First Law ...
Apparent Weight ΣFy = +FN – mg = ma The force that the object exerts on the scale with which it is in contact Two forces acting W=mg Normal force (FN) ΣFy = +FN – mg = ma Apparent Weight If acceleration is 0 m/s2, Fy = +FN – mg = ma If acceleration is upward, appar...

Usually, when I was doing free-body diagrams for homework, I would indicate that by placing the back of both arrows at the same point and making a dotted line from the tip of one arrow to the tip of the other arrow (forming a little triangle with the two vectors). That is not ...
From these results, we conclude that the G-NP behaves as a sort of quasi-particle whose motion is directed by the optical propulsion force, as observed in the kinetic diagrams shown in Fig. 3a2, b2. In the case of the uniform ξ-trap, the G-NP has a mean speed of <vφ> =...
