And that's because in Middle World, air friction is always there.

This is the force of friction or you can call it air resistance.

And not only the force of friction, you also have some air resistance

Friction

Friction

You can view it as the force of friction of the air, and let's say that is 1 N up.

Friction amount

When we move past these things in the air, we're rubbing against them and creating a lot of friction, which results in heat.

That is if there were no friction but there is friction in this situation

As the wind blows, pressure and friction perturb the equilibrium of the water surface and transfer energy from the air to the water, forming waves.

So if the engines were to shut down, all the air would bump into the plane and provide essentially friction to slow down the plane

So the first thing you might realize is if there is no friction if this was a completely frictionless boundary and there is no air resistance, we are assuming that there is no air resistance in this example

Wind creates friction on any surface.

Friction or no friction, OPEC has been, and will always be, irrelevant to market forces on the ground.

So if we start off in the x direction at 5 meters per second to the right, we won't be decelerated by air or friction or anything else.

(There is also the force of friction.)

They go in with their own friction.

There is some friction between these two

So the coefficient of friction tells us

And remember coefficient of friction are unitless

There's no friction in all of this.

In the next few videos, we'll use coefficient of friction or calculate coefficient of friction to do some more problems

I'll do a video on why sometimes a coefficient of static friction can be different than the coefficient of kinetic friction

So we can say this generally coefficient of kinetic friction is less than or equal to the coefficient of static friction

So this is the force that really overcome friction and this over here will be equal to the force of friction

These are the same surfaces is why should the coefficient of friction here why should the coefficient of static friction so this is here, this is stationary what's under place of coefficient of static friction why should that be larger than the coefficient of kinetic friction over here?

The prospects for friction between EU members escalate.

The reporting period also witnessed some political friction.

We call this the coefficient of static friction

But anyway we are talking about friction here

And friction really comes from an atomic level

The better the process, the less the friction.

You never see a situation where the coefficient of static friction is lower than the coefficient of kinetic friction but you do see situations where the coefficient of kinetic friction is lower than the coefficient of static friction that once something is moving for some reason we'll theorize why that might be for some reason friction has a little less potent than when something is stationary

So in our everyday life, the reason why we don't see these things go on forever is that we have these frictions, these air resistance or the friction with actual surfaces.

And for some materials, they might not be that different but for other materials, the kinetic friction can be lower than static friction

So you would burn up due to atmospheric friction.

What Kasparov calls process is a byproduct of friction.

This right over here is the force of friction

you could figure out this coefficient of kinetic friction

What if we could have connectivity with less friction?

We call it the coefficient of static friction because this deals with the ratio of the force of friction relative to the normal force

Maybe if my force of pushing were larger than the force of friction, or the force of friction were larger than my force of pushing.

Consider the fire that you strike ( and get by friction ) .

I'll do friction in orange 2 N to the left
