A cube is pushed such that it slides on a horizontal surface. The friction can be increased by?
2. Frictional force is developed when the block slides over the horizontal surface.
3. The frictional force acts opposite to the direction of the applied pushing force and consequently opposes the motion.
4. The relation connecting the frictional force (), coefficient of friction (), the mass of block () and acceleration due to gravity () is given by
6. From the relation above, it is clear that the “frictional force is directly proportional to the coefficient of friction and the mass”.
7. More the coefficient of friction or mass, the more will be the frictional force developed and vice versa.
8. Frictional force can be increased by Increasing the coefficient of friction which is mainly done by making the surfaces rougher.
9. Scratching the given horizontal surface or the cube with some available tool will surely increase the surface roughness which will increase the friction.
10. Increasing the mass of the block by connecting another block to it will increase the frictional force because frictional force is directly proportional to mass.
Hence, the frictional force can be increased by increasing the coefficient of friction between the block and the surface or by increasing the mass of the block.
