Friction

Friction

Friction amount

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

(There is also the force of friction.)

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

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?

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

We call this the coefficient of static 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 this is the force that really overcome friction and this over here will be equal to the force of friction

Demonstrations on the Lebanese side of the Blue Line occurred periodically at points of friction identified in my previous reports, namely Sheikh Abbad Hill, east of Hula, and Fatima gate, west of Metulla.

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.

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

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 you have 2 N of the force of friction.

So that right over there is the force of friction.

My pushing is completely balanced by the force of friction.

So what is the force of friction in this case?

Friction climbing doesn't have any sort of hard positive edges.

So it's actually the force of friction in this example

They go in with their own friction.

There is some friction between these two

So given this, let's calculate another coefficient of friction but this is going to be the coefficient of kinetic friction because now we're moving down the block.

So that's essentially the force of friction that you are overcoming

And as you can imagine, this is the force of friction

A block of ice on top of ice is much more slippery there is no friction between ice and ice, but there is friction between wood and wood

So the coefficient of kinetic friction, we'll write it as the Greek letter mu with a little k here for kinetic where it's a kind of moving friction

The prospects for friction between EU members escalate.

The reporting period also witnessed some political 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.

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

Now all of a sudden, the coefficient of kinetic friction comes to play

Nevertheless, the availability of such technologies has already begun to cause friction.

And once it's moving, the coefficient of kinetic friction starts to matter
