Moment of inertia

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…

The sport known as badminton has its origins in ancient civilisations in Europe and Asia. The ancient game was known as battledore (bat or paddle). Shuttlecock was probably originated more than 2000 years ago in the 1600s, where it was just two people hitting a shuttlecock back and forth without it hitting the ground. In 1934, the International Badminton Federation was formed, with the initial countries, which included England, Wales, Ireland, Scotland, Denmark, Holland, Canada, New Zealand…

argument. Objects do not travel up and down in a straight line; instead, objects move, when falling, in a like arch shape. Consequently, modern readers conclude that Aristotle’s argument must be incorrect. Not until Newton formed his Principle of Inertia in the 1600’s, did people know that “an object in motion tends to stay in motion, unless acted on by an outside force” and therefore that objects fell in arch shapes—not straight up and down. In other words, prior to the 1600’s people believed…

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…

stays in motion with the same speed and direction unless acted upon by an outside force. Nowadays, this law is also often referred to as the Law of Inertia. According to this law, the heavier object would have more inertia. Because it has more inertia, it also has a stronger resistance against changes in its state of motion. This larger amount of inertia offsets the larger amount of weight, so the two objects, although having different weights, would have the same rate of acceleration. 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…

earth which alters the vertical motion of a projectile. But gravity does not change its effect on the vertical motion. If you drop an object from 5 feet it will travel the same vertical distance than if you shoot the object at 100mph. What is inertia? inertia is a property of matter by which it continues in its existing state of motion in a straight line, unless that state is changed by an external force. it is mostly isaac newton's first two laws of motion. What is sir isaac newton's first two…
