 Newton’s Laws

Abstract

Have ever been in a car when the driver has suddenly applied the brakes? Have you ever tried to pull a heavy trolley or observed a plane flying in the air? If so, then you have experienced Sir Isaac Newton’s Laws of Motion. Newton’s three laws of motion are applied in everyday experience of our normal activities —from how the planets move around the Sun to how a person walks. This report is intended to help understand the meanings of the three laws of motion. The paper is also trying to find the relationship between force and motion. Throughout the whole report we will apply these laws to everyday practices.

Introduction

Sir Isaac Newton was in my mind the father of physics. His many discoveries in the field of physics prove that. He was born in 1642 and died in 1727. He had his bachelor degree and his masters of arts by 1669. Newton’s main fields were science and mathematics. He created the well-known famous calculus before Leibniz' became popular. On the other hand, Newton's most affective and famous discovery was gravity which states that {the earth's (gravitational pull) pulls objects toward it}.

Newton's First Law of Motion (Law of Inertia):

Newton's first law of motion states: an object at rest remains at rest and an object in motion continues in motion with a constant velocity (that is, with a constant speed in a straight line) (Serway, 2004).

This means that there is a natural trend of objects to resist any change in their state of motion and continue doing what they are originally doing. This is why the first law of motion is also called the law of inertia (NASA, n.d.)

If all the external forces cancel each other out, then the object will maintain the same state of motion (constant velocity). Now, if the velocity is zero, then the object remains at rest. Thus, if an additional external force is applied, then the velocity will change. However, how to determine the amount of change in velocity will be determined later using Newton’s second law of motion (Serway, 2004).

Now assume that someone parks a car on a flat road and forgets to put the vehicle into park. The car should stay in that spot. This state is called inertia.  Imagine that All of a sudden some kid crashes into the car with a bike. These kids represent an unbalanced force.  Because of this crash the car should start to move and might accelerate to 3km/h.

The result of friction between the road and tires will lead to eventual stop of the car.

Conclusion

Once all current forces are balanced, then the behavior of bodies can be expected using Newton’s first law. On the other hand, Newton’s second law explains the behavior of objects in case of unbalanced forces.

According to Newton’s third law, (action and reaction forces) act on different bodies. Thus when we apply a certain force on an object, we will directly receive the same amount of reaction on the other object that causes the action.

You can observe one of the most important applications of the three laws of motion in a space flight. The third law provides force to move a rocket, while the second law is used to convert that force into acceleration. The first law, then, keeps a space craft for instant in orbit.

Newton's Third Law: "To every action there is always opposed an equal reaction: or, the mutual actions of two bodies upon each other are always equal, and directed to contrary parts." or more commonly "For every action force, there is an equal and opposite reaction force".

Simultaneously start the stop clock and release the trolley (be careful not to push it or exert any extra force on it) 6. Stop the clock when the front of the trolley reaches the finish line 7. Record the time taken for the trolley to reach the finish, next to the relevant weight, in a table 8.

The only friction that is needed is the friction between the wheels and the ground, which is needed to accelerate quickly. Theoretical Calculations: When the angle is zero the torque is not zero as there is a constant of 0.20542, which is worked out by plotting a trend line about the theoretical points.

Displacement however takes into account not only the distance traveled but in what direction also. So for a 400m runner the distance run will be 400m but the displacement is 0m because they finish in the same place that they started.
