Another postulate of the kinetic molecular theory is that gas particles are always in motion‚ like the other states of matter. But they are different in that they undergo random translational movement. In solids‚ the particles mainly experience vibrational motion and in liquids they mainly vibrate and rotate‚ with some translational motion. Gas particles move rapidly in straight lines‚ unless acted upon by another particle or the walls of a container. This continuous contact with the container leads

Kinetic Energy: Consider a baseball flying through the air. The ball is said to have "kinetic energy" by virtue of the fact that its in motion relative to the ground. You can see that it is has energy because it can do "work" on an object on the ground if it collides with it (either by pushing on it and/or damaging it during the collision). The formula for Kinetic energy‚ and for some of the other forms of energy described in this section will‚ is given in a later section of this primer. Potential

Caselet 1 Kinetic Engineering Limited (KEL) has created a buzz in biking circles with its announcement of introducing the 250 cc cruiser Aquila of Hyosung Motors of Korea. It has generated curiosity and interest among bike enthusiasts in the country. The bike is being promoted as a ’real’ cruiser. It is fitted with a 250 cc. v-twin‚ oil-cooled engine with four valves per cylinder. It has an output of 26 bhp. with top speed of over 130 kmph. The company is the first to introduce this high-end bike

A KINETIC STUDY OF AN IODINE CLOCK REACTION PURPOSE To investigate the kinetics of the reaction that occurs between iodide and persulfate ion. You will: (1) determine the rate law‚ (2) determine the numerical value of the rate constant at room temperature‚ (3) explore the effect of temperature on the reaction and determine the activation energy (Ea)‚ and (4) investigate catalytic activity of selected metal ions on the reaction. INTRODUCTION Reaction times vary from picoseconds (10-12 seconds)

Chemical kinetics‚ also known as reaction kinetics‚ is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction’s mechanism and transition states‚ as well as the construction of mathematical models that can describe the characteristics of a chemical reaction. In 1864‚ Peter Waage and Cato Guldberg pioneered the development of chemical kinetics by formulating

material elements in contact. It is usually subdivided into several varieties: * Dry friction resists relative lateral motion of two solid surfaces in contact. Dry friction is also subdivided into static friction between non-moving surfaces‚ and kinetic friction (sometimes called sliding friction or dynamic friction) between moving surfaces. * Lubricated friction or fluid friction resists relative lateral motion of two solid surfaces separated by a layer of gas or liquid. * Fluid friction

Kinetic Art Kinetic art: the art of motion. Kinetic art contains a/or several moving parts and depends on motion for its effect. The motion of the art work can be provided in virtually any way. It can be powered by natures elements; wind‚ wave power from water‚ or heat from a fire; It can also be powered mechanically through electricity‚ steam‚ clockwork using earths natural phenomena’s ‚ gravity‚ motors‚ or even through the observer such as cranking a handle‚ or giving a push.

KINETIC ENERGY Objects have energy because of their motion; this energy is called kinetic energy. Kinetic energy of the objects having mass m and velocity v can be calculated with the formula given below; K=1/2mv² Kinetic energy is a scalar quantity; it does not have a direction. Unlike velocity‚ acceleration‚ force‚ and momentum‚ the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy‚ the standard metric unit of measurement for kinetic energy
