The two types of friction that come into play when moving two objects against one another are static friction and kinetic friction. Static friction is the force that keeps a stationary object in place. This static friction will remain in place until the applied force on the object overcomes the...

There are many forces in physics. Some of them are easy to quantify at the theoretical level. Unfortunately, static and kinetic friction are not.

Does static friction matter when rolling without slipping? Static and Kinetic Friction: Frictional forces always oppose movement. Static friction is the force resisting movement of an object from a stationary position. Kinetic friction opposes the movement of an object already in motion. ...
I used kinetic friction and did mgμ_k=mv^2/r. However, the solution is mgμ_s=mv^2/r. I am confused on why we consider static friction and not kinetic friction, thanks! mancity Thread Nov 23, 2023 Tags Friction Ramp Static Replies: 3 Forum: Introductory Physics Homework Help Shoul...
A purely mathematical explanation of why static friction is greater than kinetic friction would be extremely complicated. On the other hand, this is a question involving physics, and it should not be left up to “common sense” to determine. There is, of course, the empirical approach, and ...
