would give us the acceleration sensed by the device in each axis. We use this data to find the change in movement of mouse pointer‚ which is then transmitted serially to the host computer using RS 232 communication. 2. High Level Design We are using accelerometer to measure the acceleration of a user’s hand and integrate that acceleration into a change in position. The math behind this is very easy - using Verlet Integration‚ we would approximate the integral of the acceleration to the second degree

theorem‚ posited in 1979. However‚ Yu-kun Ho‚ a professor at China’s Fudan University in Shanghai‚ and his research group have proposed a concept of what physicists refer to as the capture-acceleration scenario to show that an electron can be accelerated by a tightly focused laser in a vacuum. In the capture-acceleration scenario‚ the diffraction from a tightly focused laser changes not only the intensity distribution of the laser but also its phase distribution‚ which results in the field phase velocity

MOTION: FERRIS WHEEL I. INTRODUCTION In this group project‚ we’ve decided to use a Ferris Wheel as an object to represent Uniform Circular Motion. A Ferris is a non-building structure consisting of a rotating upright wheel with passenger cars attached to the rim in such a way that as the wheel turns‚ the cars are kept upright‚ usually by gravity. Some of the largest and most modern Ferris wheels have cars mounted on the outside of the rim‚ and electric motors to

Objectives The purpose of the experiment is to investigate the time taken on the greatest possible precision of period of simple pendulum and the value of g‚ acceleration due to gravity and two different periods of both big and small simple pendulum’s oscillations. 3.0 Summary of Result The results of the experiment have proven the acceleration due to gravity and the precision of period of simple pendulum. Besides that‚ the length of the pendulum did influence the period and the period increased

I noticed that I have not described the rule of F=ma in either the last email or this one. Where would you suggest it be described? Somehow the details of adding forces and balanced forces were missed in the last email and also it did not make perfect sense for me to note. As far as I am concerned the khan academy does not lecture it so I am not too sure in what to do about this. I am assuming finding velocity is the sole purpose of applying the law of conservation of momentum. Is this true

Gravity is the force that keeps objects close to the earth Not only does gravity keep objects close to the earth it also keeps the solar system revolving the sun Gravity was discovered by Isaac Newton Acceleration of objects that is due to gravity on Earth is 9.8 m/s Also‚ according to Mr. Newton’s First Law‚ once the egg was moving‚ it didn’t want to stop. The container of water interrupted the egg’s fall‚ providing a safe place for the egg to stop moving so you could recover it unbroken

Abstract This purpose of this experiment was to observe the relationship between centripetal acceleration‚ centripetal force‚ and a mass M. In this experiment we used a circular motion apparatus that had a plumb bob attached to a metal shaft (that connected the plumb bob to the vertical shaft) and spring. We found the centripetal force from the spring when it was in circular motion. We hung masses off a pulley system that was attached to the plumb bob until the plumb bob was perpendicular to the

Starting from rest‚ one car accelerates to a speed of 50km/h‚ and another car accelerates to a speed of 60km/h. Can you say which car underwent the greater acceleration? Why or why not? We cannot tell which car underwent the greater acceleration without knowing the time. 30.
