fluid dynamics - Terminal velocity of a steel ball in ...

Theoretically, the terminal velocity of steel ball with diameter 3.17mm in water is about 37m/s. But in my experiment, it is only 0.7m/s. The difference is really huge. And also, I got a graph of terminal velocity as a function of square of radius of steel ball. It is a straight line, but it does not go through origin.

Ball Mills - Mineral Processing & Metallurgy

A ball mill efficiently operated performs a wide variety of services. In small milling plants, where simplicity is most essential, it is not economical to use more than single stage crushing, because the Steel-Head Ball or Rod Mill will take up to 2″ feed and grind it to the desired fineness. In larger plants where several stages of coarse ...

The ball used in a game should have high air pressure, which is explained through the law of physics. If it has high air pressure, it keeps the ball from bending when it slams against the court floor. If a ball has a low air pressure, it will form to the floor and not bounce back up, because it has less air molecules to bounce off the ground ...

Coefficients of Restitution - The Physics Factbook

The ball didn't bounce straight up because of uneven or cracked ground, which would have stopped the ball from reaching its peak height. When releasing the ball from your hand the ball rotates slightly, causing the ball to lose some of its translational energy which in turn causes the ball to not bounce as high as it would in a perfect world.

Ball bearing - Wikipedia

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls.
