And I have the normal force.
Normal force(compression/tension) N;
How to Find Normal Force.
Normal force(compression or tension) N.
Example: The normal force is 41.16 N.
N normal force of the ground supporting the rock.
This reaction force is the normal force.
The normal force of gravity is the normal force of the wedge.
The ground is providing a normal force in this situation.
And this force, in this example is called the normal force.
The ground is providing a normal force, I will do it in green.
So the normal force that I have to apply is 12.25 times the mass.
Over the magnitude of the normal force, and that is 49 sqrt of 3.
And that has to equal to coefficient of friction times the normal force.
The normal force from the wedge on this block is going to be perpendicular to the surface.
So the ground is providing an upwards force or normal force in this situation.
And there's still a normal force, the ground supporting the rock of 5 N upwards.
Well, the force I have to apply in this case is going to be the normal force, right?
And remember, the normal force is essentially the force that I'm pushing the pie with.
So they're not telling us the coefficient of friction andthen we have to figure out the normal force and all of that.
So in the case of this banana, the normal force exactly cancels out the force of gravity.
And we know that the force of frictionis equal to the coefficient of friction times the normal force.
We're sitting on the ground in the vertical direction, normal force counteracting the force of gravity.
And the normal force here, the force of contact between these two things this block and this wedge, is 49 sqrt of 3 N.
And we know this is 0.8, so we have 9.8 times the mass-- that's not meters, that's the mass--is equal to 0.8 times the normal force.
If the normal force plus the force of gravity canceled out with each other, if this equalled 0, then we would have absolutely no net force and the object would not accelerate in any direction.
And in this case, the amount of force that is being exerted by this, by the wedge on the block is the normal force, is 49 sqrt of 3.
This right here is the normal force and we will talk more about normal force in future videos the normal force is the force when anything is resting on any surface, that is perpendicular to the surface. and it will start to matter a lot when we start talking about friction.
We're gonna use this a little bit more deeply in other problems but it tends to hold true for different materials so that in the future if you have a different mass, you have a different incline butyou have the same materials given the normal force, you can figure out the budging force. .
So you know, maybe this is a certain type of wood on a certain type of wood or a certain type of sandpaper on a certain type of sandpaper whatever you're talking about, and then you can use that to make predictions if the incline was different or the mass was different or even if you are on a different planet orsomeone was pressing down on this block would change the normal force.
