Balls bounce because of the conservation of energy. When the ball is pressed down, energy is stored in it due to compression. Upon release, this stored energy is transferred into kinetic energy, causing the ball to spring back up.
A ball, falling through space, loses potential energy and gains kinetic energy. This is a way to say (in Physics equations) that it goes faster the longer it falls. When the ball strikes a hard surface, the ball is deformed and changes all the kinetic energy to elastic energy. This energy then changes back to kinetic energy as the ball recovers its shape. This is an example of an elastic collision.
There is some loss due to air resistance and thermal loss in the conversion from kinetic to elastic and back again, but the ball acts as a good demonstration that energy is conserved in physical processes.
Gravity pulls it down
========================
Funny how gravity pulls a rock down
but the rock doesn't bounce.
There must be more to it.
--------------------------------------------------
There is. Far more.
All materials (media) or objects have a degree of compressibility on interaction with another mass. They also then have a separate degree of ability to recover their original form (some may just 'dent'). This may be considered as a 'co-efficient of reconstitution' which is peculiar to each body.
Balls are designed to have high and rapid shape recovery.
(Balls can bounce in any direction wrt any local gravity, but gravity is a common accelerative cause).
Think about a rubber ball bouncing in slow motion. It hits the floor, the ball changes shape - the bottom flattens a little bit as it continues to press against the floor. Then it must straighten out and take it's natural shape and in doing so, pushes itself against the floor to round out again. The force of the ball taking it's round shape so quickly makes it go back up into the air again. So the harder you throw a ball down, the higher it will go up again.
Relation between climate condition and relief of area with rural houses and clothing?
The buildings, clothing and type of foods often reflect the climatic and topography of a given region. This is due to the availability of building materials as well as regional temperature ranges and materials to make clothing. In colder climates or mountianous regions with wide temperature ranges, wooden buildings with insulation are often found where in hot and desert climates mud brick or wattle and daub structures are found along with lighter clothing which is tigthly woven against sand storms. Foods are also different due to the climatic conditions and this can be seen in the markets of these different regions.
