By Brian H. Kaye

Intriguing studying for someone with a curious mind!

'Walking someday by means of a golfing path in Wisconsin, i used to be startled to listen to a pointy bang as a golfing ball narrowly overlooked my head and hit a tree. My better half cheerfully remarked, 'That may have killed you, you know.' I picked up the blameless having a look little white ball and checked out it with new respect.'

triggered via this perilous event, Brian Kaye has written a pleasant and informative booklet at the layout and behaviour of alternative forms of missiles from golfing balls, arrows, and slingshots to comets and rockets to outer house. you will find out about the technology of tennis and uncover the answer to questions like why a golfing ball has dimples or why a boomerang comes again. do not omit Brian Kaye's most recent, you may be amused and surprised - and research a few physics besides.

Example text

Unfortunately, we have n o record of Mrs. Joule’s observations o n Mr. Joule’s scientific pastimes! 2 Working at Storing Potential Energy in a BGW 39 at the bottom of a waterfall was exactly what he had expected from his calculations of the way in which kinetic energy is transformed into heat. For a long time people believed that heat was a fluid which flowed into an object to make it hot. The Roman word for heat was “calor” and people called this imagined fluid caloric. An instrument for measuring heat exchanges in an experiment is still called a calorimeter.

This is written symbolically in the form F=mXa where F = force, rn = mass, and a = observed acceleration. When an object falls toward the Earth we can measure that it experiences an acceleration of 981 centimeters per second per second (usually written as cm/s2 or cm s - ~ ) . This rate of acceleration is denoted by the symbol g. The observed acceleration is caused by the force due to gravity on the object. This force is identical to the weight of the body. From Newton’s second law it follows that the weight, w,of the body equals the mass, m, times g.
