Projectiles, such as the ones shot from cannons, are affected by drag or air resistance. The amount of drag exerted on to an object is affected by many different factors, such as air density and the size of the projectile. It is important to understand drag, as it affects the distance an object is able to travel if it is not influenced by outside forces, such as a cannons projectile. The equation for drag is shown below. F=pCA/2 v^2 p = The density of the air. C = The drag coefficient of the…

Roller coasters are a must see attraction in amusement parks around the world, even though they are a good source of entertainment not many are aware of how roller coasters actually function. Even though each and every roller coaster is unique all of them work under the same concept. Most roller coasters start out by ascending to a higher surface which is done to build up enough potential energy to power the carts throughout the entire ride. Energy is usually defined as the ability or…

The mousetrap car is a simple machine but its take knowledge of the laws to be effective. Newton's three laws of motion are necessary for an acceptable length or distance category. Newton's first law of motion basically states that objects like to keep doing whatever it is that they are doing. If an object is sitting at rest on a table or rolling along the floor then that object will continue to sit on the table or roll along the floor until a force is applied to the object in order to cause a…

different… In the third experiment, projectile motion… Experiment # 1 – Measuring the Acceleration of Gravity The object in motion is said to be in free fall. That is because the only force that is acting on the object is said to be the…

man need to apply to the car to get it to go in the desired direction. When you substitute the equation for numbers you would have F = 1000 * 0.05 which would equal to 50 Newton’s. A main concept that needs to be understood in Newton’s second law of motion is net force. Net force is the main focus of Newton’s second law of…

Research: According to Newton 's Second law when force is increased acceleration increases assuming that mass stays constant. a=F/m Purpose: The purpose of this lab is to prove when force increases acceleration also increases. The independent variable is amount of force applied to the Lenny Board and the dependant variable is the acceleration of the Lenny Board. 3 controlled variables are mass, surface of testing, and the Lenny Board (the weight, the amount of grease on the bearings, ECT) itself…

Rene Descartes as a famous philosopher, mathematician and scientist in seventieth century has introduced a new method for recognising and distinguishing truth from untruth. Descartes believed that this method could be useful for every body since reason is same for all people. The aim of this essay is to demonstrate Descartes’ method in three parts. In the first part it will explain that what Descartes’ method is. In the second part, it will explain the philosophical meaning of this method. And…

gymnastics, the physics involved in energy, Newton’s Laws of Motion, and angular momentum each contribute immensely to being successful in the Olympics. Learning how to master these physical science concepts can aid in becoming a strong olympic gymnast. To begin, there is the running start; this is where energy plays a major role. During a gymnast’s running start for a vault, she gains kinetic energy, which is, simply put, the energy of motion. Looking at the equation for kinetic energy (KE =…

exhibit simple harmonic motion were studied. The systems were subjected to a mass of known weight and allowed to oscillate. Afterwards, the period of each was determined. In addition, the harmonic properties in the systems and their limiting factors were determined through quantitative calculations. Introduction Any system that exhibits back and forth periodic motion (oscillator) is important since most systems are typical oscillators. Several systems exhibit periodic motion and their…

Introduction This practical was an investigation involving the use of a tennis ball and a meter ruler. The tennis ball was held and dropped at a specific height above the ground. The height of the bounce was then measured. This investigation was carried out to find out whether the efficiency of the bounce varied with the height of release of the tennis ball. If the bounce were 100% efficient, then the tennis ball would have bounce off the ground and return to the starting height. Research…
