How can you find the coefficient of friction and make sure that the surface texture is the only variable affecting friction?What Is the Coefficient of Friction:Friction is the force that exists between two surf
Friction is a factor When a disk in contact with a surface rotates, the shaft around which the disk is spinning moves forward only if the force of friction between the disk and surface is large enough to prevent slipping. The frictional force depends on the coefficient of friction between the...
To find the maximum speed with which a car can turn on a bend without skidding, we can use the relationship between the centripetal force required to keep the car moving in a circular path and the frictional force that prevents it from skidding.
Consider the diagram below. Find the velocity before friction. Mechanical Energy Conservation: An object in free fall i.e. when the only force acting on the object is the object's weight, the mechanical energy of the object is conserved. Mechanical energy conservation means that the sum of ...
