In conclusion, we can use Newton’s 3 laws of motion to maximize our rockets’ flight time. For Newton’s first law, our hypothesis stated the following: “We can apply Newton’s first law by minimizing the forces that resist motion. The way we will do this is to make the nose cone as smooth and pointy as possible. If the nose cone is too flat on the end, it will not cut through the air very well. The rocket must cut through the air swiftly, this means that resistance will be at its minimum during…

Elements of Orbital Analysis We first derive a general solution of a two-body problem subject to the universal gravitational attraction (Newton’s Law of Universal Gravitation), and then consider special cases of interest for our purpose. 1.4.1. Equation of Motion under Newton’s Law of Gravitation Using the coordinates shown in Figure 1.2, Newton’s Law of Gravitation implies that the two bodies of masses M and m, and the radius vectors r ⃗_M and r ⃗_m , respectively, would exert the…

Proving Newton’s Second Law of Motion Aim: Prove that a (acceleration) is proportional to the net force and inversely proportional to the mass. Background Theory: Sir Isaac Newton presented his three laws of motion in the Principia Mathematica Philosophiae Naturalis in 1687. The second law, ΣF = ma, states that changes in force will cause an object to accelearate and with this equation, one can figure out how much. It can be rewritten into a = ΣF / m, and thus, it can be seen that acceleration…

Using physics, we can calculate the mass of a bolt fired from a blaster used in Star Wars: The Force Awakens. First of all, we know that these bolts are not lasers based on two facts: they can be seen from the side and they do not travel at the speed of light. Thus, from there, we have to find their velocity. Rhett Allain calculated that to be about 35 m/s. He did this by finding distance and time of various bolts fired throughout the series, dividing the two measurements, and averaging out all…

Introduction In 1686, in the book, Principia Mathematica Philosophiae Naturalis, Sir Isaac Newton penned his three laws of motion. In the first law he states that, “Every body perseveres in its state of rest… unless it is compelled to change that state by forces impressed thereon.” (p. 83) His second law builds upon this principle, “The alteration of motion is ever proportional to the motive forces impressed.” (p. 83) Newton’s third law, perhaps the most famous, serves to tie the three…

Experiment-1 Simple pendulum: Aim: The main aim of this simple pendulum experiment is to investigate the relationship between the time period of a simple pendulum (oscillation) and the effective length (total length) of the simple pendulum. The three variables in Experiment-1 Simple pendulum: Independent variable: The independent variable in this experiment is the length of the string of the pendulum that could be changed. Dependent variable: The dependent variable is the time period for one…

Newton’s Laws of Motion Have you ever wondered a soccer ball continues to move long after your foot has lost contact? Or why you can coast downhill on a bicycle but going uphill you have to pedal to get to the top? Or maybe you’ve asked, why do we use seatbelts and airbags in cars? All of these seemingly complex questions can be explained by three simple rules called Newton’s Laws. For most, Newton’s Laws call up some hazy memory from childhood. You may have instantly remembered “An object in…

Gymnastics is a very large sport and is done all over the world. It is performed by both male athletes and female athletes. Gymnastics started out as a very small sport but has grown ever since. Gymnastics can be evaluated through the laws of physics. Gymnastics first started as a way to build muscle and was first one in Greece but when Rome took over Greece much of gymnastics had disappeared. That was until the Roman empire used it as a form of training in the military. At this time…

Honor can be defined by as in high respect or esteem. I would define it as something that is thought highly of and deserves to be so. It is something earned rightfully based on achievements and actions. There are many scientists who exemplify honor through their work. One of these is Isaac Newton. His accomplishments, recognition from the community, and impact on the science world define him as honorable. Isaac Newton accomplished many things over his lifetime as a scientist. He is best known…

material choice and cross-sectional area. It is clearly shown that material changes the slope of the curve based on the three rectangular beams. All three have approximately the same cross-sectional area and approximately the same area moment of inertia, so the only variable that is changing is the material. This is significant because it shows that material choice has a large…
