When you push a wooden block on a smooth steel sheet it is easy, in case of a wooden sheet it is more difficult, but when you push it on a road it becomes quite difficult. There must be greater interlocking on the road with the block and least interlocking on the steel sheet with the block. This i..

= coefficient of rolling friction R = normal reaction r = radius of rolling body This equation is applicable only for pure rolling and no sliding. It also must be noted that the coefficient of rolling friction, m r , has the dimensions of leng..

The tangent of the angle of friction is equal to the coefficient of static friction..

An oscillator, in actual practice, almost always lies in a resisting medium, like air, oil etc., where part of its energy is dissipated in overcoming the opposing frictional or viscous forces and its amplitude, therefore, goes on decreasing progressively. Such forces, which are non-conse..

Methods to Reduce Friction - Pushing a plate on a dining table gives a rough feeling but if you were to 'accidentally' drop some water and then push the plate, it would easily glide through. This is because the layer of water between the plate and the table reduces the..

The force that acts during m otion between the two bodies in contact is called the kinetic frictional force. Once the block is in motion and the value of the applied force is just equal to the value of kinetic friction, the block neither accelerates not decelerates but moves wit..

From a team of baseball players 5 players were given a test on nutrition and their scores were compared to their performance during a season. The performance scale was 1-best and 10-worst. Calculate the correlation coefficient between the players performance and nutrition score. Player's ..
