TO REDUCE FRICTION: We can use fine powder on the carrom board to reduce friction
1)increasing the roughness of the surface 2)increasing the mass of the object
By making the surface rough for increasing friction....... use any lubricating material to reduce the friction.. use rollers to decrease the friction force.. make less contact between 2 connecting materials..
Friction can be increased by reducing the speed of the moving object. Friction can also be increased by increasing the weight of the moving object.
Okay 2 ways for the friction to increase is speed and non lubricant
by increasing smothness wecan decrease the friction and vice versa
Rougher surface and more weight to the object increases friction
lubricants - 10W30, WD40
Use a surface that has a higher coefficient of static/kinetic friction and/or add more force downwards on the object.
you can get old piece of wood
Thank you
smooth the surfaces lubricate the surfacesfor gears, the shape of the tooth is importantselect the materials, some combinations of materials have lower friction than others.for something rolling, use ball bearings, air cushion or roller bearingIncrease friction:roughen the surfaces.remove lubricantselect the materials, some combinations of materials have lower friction than others.
