Varying forms of plants are able to grow in a vast number of places and environments. Plants grow in the ocean, all throughout the land, and are able to sustain life in space. The environments that the plants survive in are varied greatly as well. Different species react differently to exterior forces such as noise, temperature, and nutritional availability. People blame the differences of plant growth in urban areas from rural areas on pollution. Another factor that comes into play could be the constant vibration forces stressed upon those growths by the constant movement occurring from automobiles and other noises. Heavy amounts of vibration have been seen to be both harmful and helpful to life forms. Vibration therapy has been shown to increase bone density in a number of mammals such as deer and humans. While syndromes such as hand arm vibration syndrome effect people who are constantly under the effects of high frequency vibrations from their lines of work. There may be a parallel between the two effects of vibration of the two types of organisms. Whereas plants may either develop denser, stronger, cellular structures or acquire some sort of developmental problem due to the frequencies exerted upon it.
Vibration, in terms of physics is defined as the limited reciprocating motion of a particle of an elastic body or medium in alternately opposite directions from its position of equilibrium. When vibration occurs, its subject is more often that not stationary and rooted to a surface which it is vibrating in relation to. When talking about the effects that vibration has upon anything, Isaac Newton's laws of motion come into play to a degree.
1st Law of Motion: Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. .
3rd Law of Motion: For every action there is an equal and opposite reaction.
Newton's first law of motion relates such that unless there is a force to cause the vibration, nothing will occur.
