During the late 1890s the creation of the quantum mechanics and Einstein’s Relativity beckoned a new age in physics: modern physics. The terminology of modern physics refers to any branch of physics, such as nuclear physics or electromagnetism, which was developed in the early twentieth century or older branches that were greatly influenced by twentieth…
An object is projected horizontally at 8.0 m/s from the top of a 122.5 m cliff. How far from the base of the cliff will the object strike the ground? An arrow is shot at 30.0° angle with the horizontal. It has a velocity of 49 m/s. a) How high will it go? b) What…
Aim: Investigate any one of the factors affecting the rate of heat loss in a liquid. Introduction: Heat is a form of energy that flows due to a temperature difference. Heat transfer is a process in which energy in the form of heat energy is exchanged between the materials which are at a different temperature.…
Richard James invented the Slinky along with his wife Betty. The couple was fearful that there would be no interest in such an ordinary-looking toy. They were worried enough to give their own friend a dollar to buy one! After their first demonstration, they sold around 400 Slinkys. Slinkys were a hit. The Slinky can…
Where Chaos begins, classical science ends. Ever since physicists have inquired into the laws of nature, they have not begun to explore irregular side of nature, the erratic and discontinuous side, that have always puzzled scientists. They did not attempt to understand disorder in the atmosphere, the turbulent sea, the oscillations of the heart and…
RESONANCE: “The property whereby any vibratory system responds with maximum amplitude to an applied force having the frequency equal to its own.” In english, this means that any solid object that is struck with a sound wave of equal sound wave vibrations will amplitude the given tone. This would explain the reason why some singers…
A gun is a weapon that uses the force of an explosive propellant to project a missile. Guns or firearms are classified by the diameter of the barrel opening. This is known as the calibre of the gun. Anything with a calibre up to and including .60 calibre(0.6 inches) is known as a firearm. The…
On April 23, 1858 Max Karl Ernst Ludwig Planck was born in Kiel, Germany. He was the sixth child of a law professor at the University of Kiel. At the age of nine his interest in physics and mathematics was developed by his teacher Hermann Muller. When he graduated at the age of seventeen he…
Abstract The purpose of this lab will be to determine the mass of the cargo carried on a low friction cart by analyzing its momentum during an elastic collision. The momentum will be calculated by recording and analyzing a video, in LoggerPro3.6, of an elastic collision with two carts, one with the cargo and one…
Problem: How can an experiment be designed to measure the change in gravitational potential energy and the change in kinetic energy as an object rolls down a ramp? Predictions: Chemical energy is used by the body to lift the car 10 centimeters up onto the top of the ramp. When the energy is not being…
Cars have many devices to help them accelerate and reach a certain velocity, but slowing down the automobile is a very important function to achieve as well. Two ways cars are able to slow down their velocity is through the ability of the transmission to downshift and the brakes using friction to make the wheels…
Labs are performed in groups for data collection purposes only. Your lab report should NOT be the result of shared writing, copying, or cooperative effort. This includes your calculations. You must do this on your own. Remember to cite any references you use and do not copy from the lab sheets into your lab report. GRAPHS MUST…
Introduction A pendulum is a mass on the end of a string of negligible mass, which, when initially displaced, will swing back and forth under the influence of gravity over its lowest point. The regular motion of a pendulum can be used for timekeeping. Problem To identify the relationships between the frequency of a simple…
