HOOKE’S LAW EXPERIMENT Aim: The aim of this experiment is to determine the force constant (k) of the particular spring used. Introduction Hooke’s Law: Hooke’s Law is a law that shows the relationship between the forces applied to a spring and change in its length (extension). The relation is best explained by the equation: F= -k Δx F: Is force applied to the spring this can be either the strain or stress that acts upon the spring. k: Is the spring constant and details how hard

Silver Watkins Mrs. Williams 10th Lit/Comp 29 April 2013 Euthanasia in America Murder or Justice‚ who knows? What is the exact purpose of life? Who is it that decides our fate‚ stating/deciding whether or not it’s worth being sustained? Euthanasia is a very controversial topic that is constantly being debated by many politicians. Some of these politicians have formed groups opposing the legalization of euthanasia. These politicians’ main argument is over the immorality of it‚ but still

EXERCISE 10 Demonstrating Gas Laws Lab Group II Introduction The three gas laws discover the relationship of pressure‚ temperature‚ volume‚ and amount of gas. Boyle’s Law tells us that the volume of gas increases as the pressure decreases. Charles’ Law tells us that the volume of gas increases as the temperature increases. A third gas law may be derived as a corollary to Boyle’s and Charles’ laws. According to Gay-Lussac’s Law‚ for a given amount of gas held at constant volume‚ the pressure

Newton’s Second Law How does a cart change its motion when you push and pull on it? You might think that the harder you push on a cart‚ the faster it goes. Is the cart’s velocity related to the force you apply? Or does the force just change the velocity? Also‚ what does the mass of the cart have to do with how the motion changes? We know that it takes a much harder push to get a heavy cart moving than a lighter one. A Force Sensor and an Accelerometer will let you measure the force on a cart

Many times calculations involve numbers that were not obtained using measuring devices but were determined by counting: 10 experiments‚ 3 apples‚ 8 molecules. Such numbers are called exact numbers. They can be assumed to have an infinite number of significant figures. Other examples of exact numbers are the 2 in 2_r (the circumference of a circle) and the 4 and the 3 in 43
