One example of motion is a ball rolling down a hill. During such motion, the ball's kinetic energy is increasing and its potential energy is decreasing.

It's all ball-bearings these days
The billiard ball atom model was proposed by John Dalton.
Two uses for Osmium: >> With Iridium, an alloy used in making precision ball bearings & ball point pen points. >> As a catalyst in the synthesis of Ammonia (NH3) and in the hydrogenation or organic compounds.
They move toward the exit to escape the ball.
Perpetual motion machine
Faulty ball bearings lead to bearing failure.
Ball bearings are polished by using an abrasive cloth. Before the bearings can be polished, the polishing paste must first be applied to the ball bearing.
If you need replacements, they can be bought at a hardware store. If you mean applications/uses ... bicycle wheels have ball bearings. Lots of rolling objects that move around an axle have either needle bearings or ball bearings or roller bearings.
SIC 3562 applies to BALL AND ROLLER BEARINGS.
Turbochargers turn too fast for ball bearings. Sleeve bearings are typically used in this application.
Ceramic 8-ball bearings are the best bearings out there.
Harry Peck has written: 'Ball and parallel roller bearings' -- subject(s): Ball-bearings, Roller bearings
The advantage of using hybrid ceramic ball bearings is that they will have the capabilities of both ceramic and steel which makes the ball bearings flexible yet durable.
(compass) bearings = Peilung(lose one's) bearings = sich verirren(ball) bearings = Kugellager
