Oil reduces the effects of friction between the surfaces that are in contact with each other. If you have oil on the road it is not helpful as the moving car will slide around because the friction between the tires and road is reduced.
Lubrication of moving parts.
It is easier to push a moving object than an object of the same mass because the weight on the moving object is less and out more.... I know this doesn't quite make sense but email me at oliviabastianich@Gmail.com for a better explenation... i will help in the next 12 hours!
To make a moving object stop, you can apply a force in the opposite direction of its motion, such as braking in a car or pressing on the brakes of a bicycle. Friction between the object and the surface it is moving on can also help slow it down until it eventually comes to a stop.
It lubricates moving parts, preventing them from seizing.
this object that appears to stay in place is a reference point.
Friction can slow down a moving object by converting its kinetic energy into heat. It can also cause wear and tear on the surfaces of the object in contact. Additionally, friction can help an object grip a surface to prevent slipping or sliding.
Velocity is negative in a moving object when the object is moving in the opposite direction of its positive reference point.
the force or other moving object
it means an object is moving based on the force of friction and gravity.
Kinetic energy
The friction of a non-moving object is called static friction. It is the force that prevents the object from moving when a force is applied to it.
it may tell the speed of the moving object
