Newton’s Laws of Motion and Force and Bernoulli’s Principle of Pressure

Newton’s Laws of Motion and Force and Bernoulli’s Principle of Pressure

Newton’s Laws of Motion and Force are broken down into three laws. These laws define the concept of a force and describe motion, used as the basis of classical mechanics. The three laws of motion are fundamental to mechanics, or the study of objects in motion. These laws may be stated in a number of ways, assuming they contain all the components identified by Sir Isaac Newton (“Newton’s Laws of Motion”).

The first law of motion states that an object at rest will remain at rest and an object in motion will remain in motion, at a constant velocity unless or until outside forces act upon it. This means that there is a natural tendency of objects to keep on doing what they're doing. All objects resist changes in their state of motion. In the absence of an unbalanced force, an object in motion will maintain this state of motion. This law is commonly referred to as the law of inertia (“Newton’s 3 Laws of Motion”).

Newton’s second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law explains that the acceleration of an object is depends on two key variables; the net force acting upon the object and the mass of the object. The acceleration of an object is determined by the net force acting upon the object, and upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased (“Newton’s Second Law”).

Sir Isaac Newton’s third law of motion pertains to the push or pulls on an object that is a result of its interaction with another object. These...
