Radin, Robin, Executive Producer has reference to this Academic Journal, PHwiki organized this Journal Normal ForceNormal ForceNormal as long as ce is a as long as ce that exists due to contact between two surfaces.Normal as long as ce is always directed perpendicular to the surface.(The Normal is any line perpendicular to a surface. We use it to assign a direction to a surface).The magnitude of Normal Force on an object will change to suit a particular situation ( in addition to keep Fnet=ma valid).Warning!!!! FNET FNReaction ForceSometimes FN is called the Reaction Force(R). In the case on the right, the box is pushed into the wall, consequently, the box pushes the wall. If the box pushes the wall, (according to Newton 3) then the wall must push back on the box there as long as e FN is the reaction to the box pushing the wall.

Normal ForcePerpendicular to a surfaceYou push a box into the wall (to the left). The normal as long as ce on the box is to the right, away from the wall.A box sits on a slope, the normal as long as ce on the box is diagonally up in addition to to the right, perpendicular to the slope.A box sits on a horizontal surface, the normal as long as ce on the box is directed upwards, perpendicular to the surface.Normal ForceIt changes depending on the situationThe magnitude of Normal Force on an object will change to suit a particular situation.Consider the following situations of the same box.You push a 6.0 kg box against a wall with 120 N of as long as ce (dont ask me why, you are the one doing it!).Since you apply 120 N of as long as ce, since the box does not accelerate into the wall, the wall must be pushing back on the box with 120 N of as long as ce.If you increase how hard you push to 180 N, Normal as long as ce will also increase to 180 N.2. Now the box is just sitting on the floor.It is not accelerating, so the net as long as ce on the box is 0.N.Up as long as ce must be equal to down as long as ce.Fg=FNFg=mg=6.0×9.8Fg=58.8 N= 59N.Since the net as long as ce is 0, the magnitude of the normal as long as ce must also be 59 N.
2. Instead, you try to pick the box up by applying an upwards as long as ce upwards of 20. N.Do you successfully lift the boxHow do you knowThe box is not accelerating, so the net as long as ce on the box is still 0.N.Total upwards as long as ce must be equal to down as long as ce.Now there is one more upwards as long as ce.Fg=FN+FAFg=mg=6.0×9.8Fg=58.8 N= 59N.Fg-FA=FNSo FN has reduced to 39 N.Elevator ProblemAnother situation in which we see changes in normal as long as ce, is in an accelerating reference frame.Consider a 100. kg person st in addition to ing in an elevator that is moving downwards, in addition to accelerating at 1.8 m/s2.Can you determine the Normal as long as ce on the personStart with a free body diagram You might find it helps to put al little arrow off to the side that shows the direction that it is accelerating Write out your Fnet equation. (as in Winning as long as ce Losing Force )Rearrange to leave FN by itself You win!!!© 2005 Warner Bros. Entertainment Inc.

.ContinuedApparent WeightWeight: Weight is the as long as ce of gravity acting on us (Fg) Apparent weight: We feel as heavy as the magnitude of the as long as ces that support us. This is a result of things like We sometimes refer to the impression of reduced weight when in an accelerating reference frame as Apparent Weight, but this is in fact governed by the Normal Force (the as long as ce that supports us)When we are in an accelerating frame of reference, we have an apparent weight governed by FN. Think about astronauts in the space station, or people on the vomit comet. Or just close your eyes in addition to focus on the sensations on your body when you are in an elevator.https://www.youtube.com/watchv=d57C2drB-wchttps://www.youtube.com/watchv=k3xSYRa9G0ghttps://www.youtube.com/watchv=2V9h42yspbo
