In particular, at the lowest v (30 mm/min), the F value rises by approximately 39.6% as ω grows from 1200 to 2500 rpm, whilst at the highest v value (100 mm/min) it increases approximately 23.9%. Figure 7. WebAs you can see in the formula of kinetic friction there is no mention of the force you're aplying, it's only proportional to the kinetic friction coeficient and to the normal force.

WebMay 14, 2012 · Once the speed is reached and acceleration is zero, then only frictional force applies. 10 meters/second is a pretty good clip. Depending on the frontal area of the … WebA car's speed is often determined by the friction between its wheels and the road. When you drove your toy car over the smooth tile, the wheels were met with little resistance. Try sweeping your finger against the tile --is it met with any resistance, anything that somehow stops it from moving forward? Webhow does speed affect the friction between a road and a skidding tire.
