ball bearing uses

As rolling friction is less than sliding friction, ball bearings and roller bearings are also used for decreasing friction. Small balls or rollers made of steel are placed between the moving parts...

They are made in various designs to reduce friction. They reduce friction because rolling friction is smaller than sliding friction. These bearings are also lubricated to further improve their function. ..

/roller bearing help to convert sliding friction into a milder form - rolling friction. Rolling friction is lesser than sliding frictio..

Jim can jump with an initial velocity of 4 feet per second. To catch the ball hit by a baseball hitter, he has to jump 11 feet. The equation for the height of his jump is h = -16 t 2 + 4 t + 4. Using the discriminant, find whether he can catch the ball. => No or Yes..

When steel slides over an alloy of lead, the friction is less than when steel slides on steel. Hence bearings are packed with an alloy of lead...
