As the ball has less KE and is travelling slower it becomes stationary faster at the top of its arc. Therefore the height that it reaches is less high. As velocity increases air resistance increases in proportion to the square of the velocity. This means that the faster that the ball travels the larger the force of air resistance upon it.

The mechanical energy of a bowling ball gives the ball the ability to apply a force to a bowling pin in order to cause it to be displaced. Because the massive ball has mechanical energy (in the form of kinetic energy), it is able to do work on the pin. Mechanical energy is the ability to do work.
Air Compressor Operation Description of Two Stage and Theory Now let's discuss the actual operation of an air compressor with indicator diagrams. Operation To understand the operation of an air compressor, let us assume the cycle and indicator diagram for a simple single stage reciprocating air …
During the experimental tests, the room remained in ambient temperature, around 21 C, the air density was assumed to be 1.079 kg/m 3 and air dynamic viscosity to be 1.83x10-5 Pa.s. Measurements were made in duplicates for each experimental test to get an average value of the difference of pressure, and to guarantee the data repeatability.

Oct 04, 2003 Sharp dies are often used commercially to produce polymeric fibers in the melt-blowing process. In these sharp dies, the flow field results from two similar converging plane jet nozzles with no space between the nozzles. This study utilizes a computational fluid dynamics approach that is validated through experimental data to investigate the effect of recess or excess (inset or outset) of the ...
For the preparation of the pigment, the clay from the IOT was fired at 950 C for 120 min in a muffle furnace (brand Jung JB3013), with temperature step of 3 C/min. Subsequently, it was grinded in a planetary ball mill (brand Retsch PM 100) for 10 min in rotation of 400 rpm. This fraction was adopted as pigment (P-IOT).
