Newton’s 1st Law of Motion

Newton’s first law of emotion asserts that an object which is at rest will always remain at rest and an object in motion will equally remain in its motion with the same velocity unless one acts upon it through an unbalanced force. Before discussing or explaining the drawn object, it is necessary to define some of the key terms which are used in explaining Newton’s first law of motion. Velocity refers to the speed of a given object in a given specified direction while the unbalanced force typically means an external force which transforms the motion of the specific object. It is also important to note that when an object is at rest or even moving at a constant velocity, forces which act on it are referred to as balanced forces (Zimba, 2009).

For instance, when examining the drawing above, one can observe that the cup of coffee is resting on the kitchen table. The force of gravity which is pulling down is balanced by force available at the kitchen table which is pushing up on the cup of coffee. If the coffee is to be moved, one must apply an external force to disrupt the balance, and it was important that one has to have the muscle which is strong enough in applying such a force so that one can enjoy the cup of coffee. Newton’s first law of motion can also be termed as the law of inertia.

Newton’s 2nd Law of Motion

Newton’s 2nd Law of Motion states that acceleration will be produced when an unbalanced force acts on a mass and the more mass the object has, then the more net force will be applied in moving it. According to Newton’s 2nd Law of Motion, when a force is acting on an object, the object (mass) will be forced to accelerate in the direction of the force. If at all the mass of the force is held at a constant rate, enhancing the force will subsequently improve the acceleration. However, if the force available on a given object is held constant, adjusting the mass will also lead to a decreased acceleration. In simpler terms, force and acceleration are indeed directly proportional at the same time the mass together with the acceleration is inversely relative (Croce, 2004).

As mentioned earlier, Newton’s 2nd Law of Motion asserts that acceleration of a given object is usually influenced by the net force which is applied to the object and the mass of the object as demonstrated in the drawing above. Acceleration will be felt when the man in the picture manages to move the car after applying a force which will cause an acceleration. The increase in the number of the people applying the force on the vehicle will influence the rate of acceleration, and the net force is usually measured in units known as Newton, and the net force will also play a significant role in influencing the acceleration direction. The vehicle will accelerate in the same direction in which the man applies the net force which is acting on the motor vehicle which is the object. It is also notable that the net force (man) which is acting on the object (vehicle) is actually directly proportionate to the vehicle’s acceleration and this implies that the superior the net force, the better its acceleration.

Newton’s 3rd Law of Motion

Newton’s 3rd Law of Motion states that the forces usually act in pairs (Croce, 2004). A good example can be observed in the picture below which demonstrates a boy who is playing with the dog’s toy, and there is an existing force from the toy on the boy, and the two forces create an interaction pair. This implies that forces usually produces an interaction pair. Contemplate the boy (A) as one of the systems while the toy (B) as another. What are the forces which are acting on every system? To understand this, one should picture the boy (A) pulling on the toy while the dog is pulling the toy from the boy. It is observable that every system exerts a force on each other. The forces of interaction between the two can be identified as the F(A on B) and F(B on A); one should notice the symmetry in A on B as well as the B on A.

Typically, the forces F(A on B) together with F(B on A) are called interaction pair; and they are a collection of two forces which are in opposite directions, have the same magnitudes and are acting on various objects. In some situations, an interaction pair can be termed as an action-reaction pair and this advice that one will influence the other one; nonetheless, this is not the reality. For instance, from the picture above, the force of the boy which is pulling on the toy does not impact the toy to pull on the boy as the two forces can either occur together or not. Specifically, Newton’s Third Law of Motion asserts that several forces usually happen in action-reaction pairs.
