Physics Lab: The Hooke’s Law and SHM Science Department SPH 4U Introduction Hooke’s Law is the law at which explains how the force exerted by an elastic device varies as the elastic device compresses and stretches. In order to mathematically analyze the force the equilibrium position is when the spring is at rest. When force is applied and the spring is being stretched the spring has the tendency of pulling back to the equilibrium position and vice versa. If the force applied to the spring

Sir Isaac Newton I am writing about the famous Isaac Newton. Even though Isaac Newton was born January 4‚ he was born on Christmas day. He is an important part of science that changed the world by giving use the three laws of motion and the concept of gravity. I care because his discovery led to many other discoveries today that would not have been discovered without his three laws. The three laws affect me because without it we wouldn’t know useful thing such as why things like swings and see-saws

Springs and Oscillators Abstract Two experiments were conducted to find the spring constant of a steel spring‚ and another experiment using a rubber band was performed to see if it agreed with Hooke’s law. The spring constant was found statically by measuring the distance traveled as different masses were applied‚ and also found dynamically by measuring the period of a mass hung from one end and pulled down then released into vertical oscillations. We found that the rubber band

To what extent are Religious Monuments still used for what they were built for today? Discuss. Firstly‚ today religious monuments are used for tourism. Many people come from all over the world to visit famous monuments‚ which used to be used for religious practices or still even do. Some examples are St Paul’s Cathedral‚ Westminster Abbey and the Washington monument. During the day Westminster Abbey is full with tourists who want to learn about what used to go on inside these places. Another

Isaac newton is undoubtedly considered one of the greatest mathematicians to ever grace the earth. He evolved mathematics in ways nobody else’s thought was possible. In my opinion‚ he is one of the most defining mathematicians of all time. Sir Isaac newton was born on 1/4/1943 in the United kingdom. He was the son of a local prosperous farmer‚ also named Isaac Newton‚ who died three months before he was born. At age three‚ Isaac’s mother then remarried a minister‚ leaving him in the care of his

Aim: To determine a value for the spring’s force constant‚ k. Introduction: Hooke’s Law indicates the relationship between the amount of extension‚ e‚ of a spring to the size of the force‚ F‚ acing on it. This relationship may be written as :- F = ke F = ke where k is a constant for which particular spring you are using. It is the force constant of the spring. * The force applying on the spring‚ F‚ is denoted by Newton in SI Units. (N) * The amount of extension of the spring
