Centripetal Force: The center-seeking force Group Members: Joshua Velez‚ Patrick Hannigan-Devine‚ and Eric Guidarelli PURPOSE: To move in a circle F=ma is required‚ where acceleration being the rate of change of velocity with velocity being both magnitude and direction. Magnitude of acceleration can be found by a=v2R. The relation of these two is found in centripetal force F=mv2R. This lab will prove the relation of the first two equations. EQUIPMENT: * Centripetal Force Apparatus

Apollo 13 Essay Have you ever wondered what it would be like to fly in space or work on the crew at NASA that helps the astronauts get home safely? These two jobs both use many of the laws of physics. In fact‚ almost everything they do involves physics. Apollo 13 is a movie that epitomizes what those jobs are like and how much physics is required. The three main laws of physics in the movie were Newton’s Law of Universal Gravitation‚ Newton’s First Law‚ and Newton’s Third Law. One main law in

Conclusion: Category 1: Momentum was found that after the collision was less than before the collision by 10%. This was not what has been expected‚ so the difference was fairly significant. This happened because of friction‚ when the two pucks collided‚ they have lost a bit of their momentum‚ so the momentum after the collision differed. Kinetic energy differed more than what was expected‚ it was significantly less after the collision‚ the difference before and after the collision was 63.7%‚

the Swinging Wonder Recently‚ an American manufacturer developed a scientific demonstrator named « the Swinging Wonder ». Intended for use in schools as an aid in understanding certain principles of Physics or in the home as an educational toy‚ this small demonstrator quickly became an object of fascination for both the science teacher and the layman. The purpose of this device is to demonstrate Sir Isaac Newton’s law of motion‚ in which action and reaction are equal and opposite.

Newton’s Three Laws Newton’s three laws of motion are laws or “rules” as to why objects move or don’t move they way they do. They tell us why things that move or at rest stay that way‚ or why the speed up‚ or simply what kind of things it takes to move objects. Newton’s three laws are very important because before he discovered these no one really knew why objects did what they did‚ they simply just did it. I care about these laws because I’ve learned so much that I never really understood nor knew

PHYSICS 1 MIDTERM EXAM REVIEW #2 1. A 6.0-N force and an 8.0-N force act concurrently on a point. As the angle between these forces increases from 0° to 90°‚ the magnitude of their resultant (1) decreases (2) increases (3) remains the same 2. A car increases its speed from 9.6 m/s to 11.2 m/s in 4.0 s. The average acceleration of the car during this 4.0-second interval is (1) 0.40 m/s2 (3) 2.8 m/s2 (2) 2.4 m/s2 (4) 5.2 m/s2 3.

Circular Motion Uniform circular motion is the movement of an object or particle trajectory at a constant speed around a circle with a fixed radius. The fixed radius‚ r‚ is the position of an object in uniform or circular motion relative to to the center of the circle. The length of the position vector of the circle does not change but its direction does as the object follows its circular path. In order to find the object’s velocity‚ one needs to find its displacement vector over the specific

Theological Impact on the Theories of Descartes‚ Maupertuis‚ & Faraday René Descartes‚ Pierre-Louis Moreau de Maupertuis‚ and Michael Faraday all lived in a time when religion was king‚ but science began experiencing great progress and advancement. While all accepted God‚ theological considerations affected their theories in different measures. Descartes relied heavily on the immutability of God to formulate his theories‚ Maupertuis accepted the presence of an all-powerful being in control‚
