What about static friction? When you weren't able to move ... If not, that means the box will start sliding down the ramp, and you may have a problem. The first thing we need to do is draw a ...

However, to generate motion in the first place, it is not sliding friction but static friction that must be overcome. Static friction is typically larger than sliding friction and a result of the ...

If the ramp is inclined far enough, the frictional force will grow until the point that it is unable to prevent the mug from sliding. To put it this way: once the static friction has been overcome, ...

Finally, the block begins to move. As the body is sliding along the horizontal surface, the spring scale again shows a smaller force. Why? Initially, static friction holds the object firmly in place.

That is to say, the frictional force pushes in a direction to try to prevent sliding. If the two surfaces are stationary relative to each other, we call this "static friction." The maximum ...

For example, this cup on the table. Absolutely. They can best be divided into dry friction, which can be static or sliding friction, rolling friction and fluid friction. If they're not moving it's ...

Notice that there is a different coefficient for static and kinetic (sliding) friction. On to the first experiment (using the DIY force scale). Here I have a block on a table. I am going to pull ...

As a result, and perhaps counterintuitively, the surface starts sliding more easily, and the relative resistance to motion—the so-called static friction coefficient—decreases. Using a simple ...
