Force: This can be defined as a pushing or pulling action that causes a change of the state of a body. A long jumper who wants to increase their degree of force will need to increase their weight‚ but this can negatively affect their speed‚ so it is vital to get the balance right. The law of reaction also applies to movements that occur in the air. In these situations the equal and opposite reaction is shown in movements of other parts of the body. A long jumper‚ for example‚ will bring the arms

Continuum Hypothesis in Fluid Mechanics The macroscopic behavior of fluids makes them appear to be continuous. However‚ when viewed at the microscopic scale fluids cannot be viewed as continuous. The fluid under consideration will have molecules bombarding each other. It is not possible to declare the fluid velocity at a point as there is no guarantee that the fluid molecules are present at that point at a particular instant of time. When we calculate the fluid velocity or density at a point it

Classical and Quantum mechanics are the two main fields of mechanics in physics. Classical mechanics came a few hundred years before Quantum mechanics. Subsequently it is less accurate and less reliable then the more recent mechanic field of Quantum mechanics. Despite being outdated‚ Classical mechanics can still be used for many everyday problems with bigger and slower moving objects. However‚ when dealing with extremely fast moving or small subatomic particles a Classical approach will not

When an object (stone‚ spear‚ arrow or bullet) is thrown‚ hurled or shot in the air‚ the object is a PROJECTILE (“Projectile”). The study of projectile is important because it must be realized that they are very much part of man’s daily life then and now. Whether man likes it or not‚ he encounters and uses projectile in his everyday life. Our hunting ancestors threw stones and spears on animals to kill them for their food. In today’s sports‚ balls follow projectile motion such
