2. Treatment/General Procedure - the manner & sequence by which each experiment or set of observations were done & how measurements were obtained should be described in detail. Avoid using the "recipe style" when stating the step-by-step procedure. Use the narrative form in the past tense. 4. Results and discussion - this may be divided into sub-sections describing each set of experiment or observations. 1. Findings - the data maybe presented in full & discussed descriptively in the test or these

Experiment 1: Simple Harmonic Motion Dominic Stone Lab Partner: Andrew Lugliani January 9‚ 2012 Physics 132 Lab Section 13 Theory For this experiment we investigated and learned about simple harmonic motion. To do this we hung and measured different masses on a spring-mass system to calculate the force constant k. Simple harmonic motion is a special type of periodic motion. It is best described as an oscillation motion that causes an object to move back-and-forth in response to

This year in science‚ we were paired up in groups to build a car powered only by a rubber band. There was a lot of physics and thought put behind the planning of our car. The rubber band moved the car by storing up elastic potential energy which then turned into kinetic energy when released. Newton’s Laws of Motion also come in handy when thinking about how to keep the car moving. “An object in motion stays in motion.” There was also a lot of thought put into the wheels. We had to be aware of the

surface‚ accelerating because of an unbalanced force. The rate at which an object travels down the slope is dependent upon how tilted the slope is; the greater the tilt of the plane‚ the faster the rate which an object will slide down. Thus‚ if a physics cart is released on at a steep slope‚ the acceleration of the cart is expected to roll down the slope at a faster rate. As shown in figure 1‚ when a cart is released on an inclined plane‚ there’s always two to four forces acting upon the cart – the

8th physics light reflection refraction eyes defect and dispersion The ray of light which falls on the mirror surface is called incident ray. The point at which the incident ray strikes the mirror is called the point of incidence. The ray of light which is sent back by the mirror is called the reflected ray. The ‘normal’ is a line drawn at right angles to the mirror surface at the point of incidence. The angle between incident ray and normal is called the angle of incidence. The angle between

The Physics of Rainbows As we are coming down to the final weeks of winter‚ the days are getting longer‚ and it is slowing starting to warm up. We are all looking forward to springtime‚ with its promises of flowers and rain. Along with this rain brings reminders of rainbows. As Donald Ahrens says in the Meteorology Today magazine‚ “rainbows are one of the most spectacular light shows observed on earth (About).” In fact‚ one of the best ways to view a rainbow at it’s utmost
