Newton's First Law is basically about the concept called Inertia which is defined as the tendency of an object to remain at a constant velocity. There are two parts in Newton's First Law and they are: 1) objects at rest ( velocity, v =0) will remain at rest unless acted upon by an unbalanced force and 2) objects moving at constant velocity (v 0) will remain moving with that velocity and direction unless acted upon by a net external force…

Understanding the concept of a net external force is crucial in understanding Newton's first law. To illustrate this, consider a rope being used in a tug of war. There are two opposing forces in the activity but if the two sides pull with the same force then the rope would not move. That is, the two forces cancel each other out resulting to no net force on the rope. Thus, forces may be acting on an object but they are applied in such a manner that they cancel each other's effects. Force is a vector so it is important to take account of the direction. The result is that there will be no change in velocity since Force, F = 0. In calculus, this would be represented as dv/dt = 0 when F = 0 or simply, there is no differential change in velocity when there is no net external force. This is illustrated in the following;
Figure 1. A Physics book pulled downward by gravity but the table exerts an upward push. The book does not move because the two forces cancel out. Note that the table is an inanimate object but is exerting force. The occurrence of force applied by the table will be explained further in Newton's Third law.
2.0 Newton's Second Law of Motion: Force and its Representation
"The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object."

While the first law describes the behaviour of objects where the F = 0, the second law is concerned with the situation where there is an unbalanced force. If F 0, then dv/dt is 0. In simple terms, the object accelerates, a, the rate of which is equal to the force applied divided the mass of the object. The acceleration of an object produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and is inversely proportional to the mass of the object. In equation form:

Newton's Second Law is used to account for the acceleration of an object and not the motion itself. This law made it possible to quantify the concept of force. Whereas before it was previously defined as a push or pull, force was now quantified using the unit Newton (N). 1 N is equivalent to the force required to impart a 1 kg mass with acceleration of 1 m/s/s. The vector nature of force is also highlighted in the second law and gave rise to the need for constructing free body diagrams (FBDs). A free body diagram is a simple representation of an object with arrows. These arrows represent the forces together with its direction and intensity. In constructing FBDs, it is essential to take full account of all the forces acting on the object including action-at-a-distance force. An illustration of FBDs and unbalanced forces are shown:
Figure 2. The object is acted upon by forces which are unbalanced in all three cases thereby resulting to an acceleration of the body mass.

...; he ended up altering and changing the face of each of these disciplines, as we know them. It was during his time at Trinity that Newton discovered the binomial theorem in mathematics. He then, during these brief four years of undergraduate work, began to develop infinitesimal calculus. Even with these major accomplishments, amazingly he still graduated relatively unnoticed and simply returned to his family home. It was there that he spent two years engrossed in theories on calculus, optics, and the law of gravitation. Upon completing them, he was lured back to Cambridge and became a fellow at Trinity. It was in this capacity that in addition to his scientific pursuits, he became intrigued by philosophy...

...Friction Newton’s second law was put up to investigate the relationship between massforce and acceleration. Finding coefficient of static friction, µs and the coefficient of kinetic friction, µk. requires set formulae to determine the acceleration of a body in relation to the force and mass of an object. It is widely believed that the natural state of an object is when it is at rest. Forces are responsible for the movement of a body. To test Newton’s law, various experiments can be conducted on the acceleration and proportionality of an object. A proof of an increase or decrease in mass of the Newton’s...

...Friction by Tsing Introduction Arguably, the book by Tsing stresses that globalization is a system that unites the world into asingle imperial system. She further states cultural differences are a critical concept since this can lead to rearrangement of power and culture. Unequal encounter, heterogeneity, and diversity concept require careful handling. According to her friction helps in understanding universalism: freedom, prosperity, and knowledge (Tsing, pg29). She questions the ability of globalization in forging connection yet it posits that unity of purpose is unnecessary. Forging universal connection is facilitated through the flow of information. The flow of information is critical in engaging the...

...of applications such as multiple-angle identities, series for e, derivative of the power function, and nth derivative of a product. The discovery of calculus was another significant achievement of Newton in mathematics. According to the Oxford Dictionary of English, calculus is defined as “the branch of mathematics that deals with the finding and properties of derivatives and integrals of functions, by methods originally based on the summation of infinitesimal differences” (247)ii. The development of the calculus gives the modern world a systematic way for the accurate calculation of volumes and other quantities that were not possible earlier. Finally, Newton’s three...

...Lab 4: Friction Friction: Determination of µs and µk Interaction of two bodies on the surface always involves contact forces. Contact forces are grouped into two (normal and friction forces). The normal force is perpendicular to the contact force while a friction force is parallel to the contact surface. On the other hand, a friction force is a type of force that acts on a moving body and it is always parallel to the motion of the object. There are two types of friction called kinetic and static friction. A static friction force (fs) acts on an object at rest while kinetic friction (fk)...

...Friction Friction Theory: Friction is a force that always tries to limit the pull or push force when one object is makes contact with another surface. In more simple way, friction is the force that restricts the motion of the one object sliding at another object. Friction is also important in many matters, like cars and vehicles use the friction between tires and roads to move the vehicle. On the other hand, it produces wear and tear in the engine parts when they slide over one another. In order to estimate the friction proper mathematical systems are utilized to evaluate the force of friction between the...
