What is the force that accompanies a moving part?
The force that accompanies a moving part is typically called kinetic friction. This force acts opposite to the direction of motion and arises due to the contact between the surfaces of the moving part and its surroundings. It resists the movement of the part and is proportional to the normal force pressing the surfaces together.
Is the friction between car tires and pavement greater when the car is at rest or in motion?
Interesting - static friction is greater than moving friction; but if the car is not in a skid, then the part of the tires in contact with the road is not moving ... thus static friction holds in both cases.
What do some machine use to lower friction between moving part?
Machines use lubricants such as oil or grease to lower friction between moving parts. These substances create a thin film between the surfaces, reducing direct contact and minimizing friction and wear. Additionally, materials with low friction coefficients, like certain polymers or coatings, can also be used to reduce friction.
What is the moving part of a lever?
The moving part of a lever is the rigid bar or beam that pivots around a fulcrum. This moving part exerts a mechanical advantage by magnifying the force applied to it.
What is the most important part of a lever?
The most important part of a lever is the fulcrum, which is the fixed point around which the lever rotates. It determines the mechanical advantage and efficiency of the lever in moving or lifting objects.
How brakes stop a bicycle?
By creating friction between a moving part and a stationary part.
Where in an engine does friction occur?
The pistons, the cam(s), the lifters, every moving part will experience friction.
When a car goes for servicing grease is applied on its moving part?
to reduce friction
How can friction be un- useful?
In any part that you want to keep moving, like a spinning wheel, friction is just a nuisance.

Which part of a bicycle are designed to decrease friction?
Any bicycle part that makes contact with another part but needs to move to function must have friction reduced. The wheels bearings, steering head, pedal bearings in both the hub and pedal, and the chain links all are designed for minimum friction but they also need lubricant.

Where does abrasion happen the most?
Abrasions are most commonly seen on the skin, where friction or rubbing can cause superficial damage to the top layers of the skin. They can occur on any part of the body that experiences contact with rough surfaces or repetitive rubbing, such as the knees, elbows, or hands.
How rollers reduce friction?
when we are moving on rollers .....only a very small part of the roller is in contact with the ground ......this means only a very smaal part of the rovver get s stuckein the uneven surface of the ground ...as a result there is less friction..!!
What is the difference between sliding and rolling and kinetic and static friction?
Sliding friction is the friction between the body and the surface on which the body is sliding. Static friction however, is the friction when the body isn't moving when you aply force to it. The force of static friction is the same as the force you are pushing the body UNTIL it moves!..It's a fact that the static friction coefficient is a bit bigger than the sliding friction coefficient.
How does an object move on a rough and on a smooth surface?
It is on smooth surfaces because the amount of friction is less.
