Measuring g via Free Fall - NUSTEM

3/8/2020· What’s in the Film. The film shows four different methods of measuring g using a falling object: Drop a ball and time its fall with a stopwatch. Drop a ‘g-ball’, which times its own fall. Drop a ball through light gates. Use an electromagnetic switch to release a ball bearing, with triggered timing.

Dropping the Ball (Slowly)

If the ball is dropping at a steady speed, this force should just balance the weight of the ball. The mass is 0.05 grams, which is 5.10 -4 N. But we should also have subtracted off a buoyancy force, which would get this closer to 4.10 -4 N.

S Bearings, EZO bearings, Bearing Relubriion Services - Ball Bearing …

Greases have speed ratings sometimes called “DN” ratings. The calculation for the “DN” of an appliion is as follows: Speed in rpm x (bearing ID + bearing OD) ÷ 2. Assume a bearing rotates at 20,000 rpm. The bearing ID is 8mm and the OD is 22mm. The above formula produces a DN of 300,000 so the grease should be rated above this figure.
