AS Level Physics: Terms & Definitions:- Measurement Random errors are errors of measurements that result in a scatter of readings about a mean value. Systematic errors are errors of measurement which occur according to some fixed patterns such that they consistently give out an over-estimation or under-estimation of the true value. Accuracy is a measure of how close the results of an experiment agree with the true value. Precision is a measure of how close the results of an experiment

Physics of Car Crashes INTERNAL - Notes INJURIES TO A HUMAN: During a car crash‚ there are three different collisions that occur. The first one is the collision of the car and the opposing object‚ the second is the human inside the car and the car itself. The final collision is the ones that occur within the human body itself. BRAIN: The human brain is protected by the cranial cavity or the skull. The brain is suspended in a substance called the cerebral spinal fluid‚ which is denser than the skull

Title IX came from the Education Amendment of 1972. The law states that “No person in the United States shall on the basis of sex‚ be excluded from participation in‚ be denied the benefits of‚ or be subjected to discrimination under any education program or activity receiving federal financial assistance. The amendment in 1987 expanded the definition of program or activity to include all the operations of an educational institution‚ governmental entity or private employer that receives federal funds

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

Murphy Grand Canyon University: Physics 1 Lab September 5‚ 2013 Testable Question: Circular objects; what happens to the circumference as the diameter changes? Hypothesis: As the diameter increases‚ the circumference will increase in a proportional linear way. This is because as the diameter increase‚ the object will as well. Variables: Independent- The diameter of the circular objects. Dependent- The circumference of the

The Ballistic Pendulum Crime Lab Physics You are a criminologist‚ and have been given a gun which has been used in the commission of a crime. Both prosecution and defense claim that "muzzle velocity" (speed of the bullet as it leaves the gun) is crucial to the case. Your job...FIND IT! Shown below is a diagram representing a "ballistic pendulum." The bullet is fired into the block‚ the bullet-block combination rises by a height h as shown‚ a little physics is applied‚ and ...voila!...there

Experiment 9: THE TANGENT GALVANOMETER; PURPOSE: In this experiment we will measure the magnitude of the horizontal component of the Earth’s Magnetic field by the use of an instrument called a tangent galvanometer. INTRODUCTION: A tangent galvanometer consists of a number of turns of copper wire wound on a hoop. At the center of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of
