LAB: Force Lab Research Question: How does the change in mass of an object affect the force and time while the object is moving down a height of 31cm? Hypothesis: My prediction is that the greater the mass of the toy car the larger the force of gravity‚ as the product of the masses of two objects increases‚ the force of gravity that attracts them toward each other increases. According to Newton’s law of universal gravitation‚ “gravity and mass are directly proportional” hence‚ creating a greater

Centrifugal Force Apparatus HFC21 Objective: The object of the experiment is to verify that the centrifugal force varies in direct proportion to 1. The mass of the rotating body M (Experiment parts 1 and 2) 2. The square of the speed of rotation ω (Experiment part 3) 3. The radius of gyration k (Experiment part 4) In accordance with the formula; F = Mω2k Apparatus: Centrifugal Force Apparatus HFC21‚ Cast iron calibrated weights arranged as in Figs.1 and 2.

Labor force Labor force is the total number of persons available to supply the labor for the production of economic goods and services. In other words‚ it is the total number of people of working age in a country who are able and willing by law to work. It is the active or working population and it comprises all persons who have jobs and those who are seeking for jobs in the labor market. They are normally found between the age bracket of 18 to 65 years. Working population varies from one country

The five competitive forces that shape strategy Introduction The five competitve forces that shape strategy also know as Porter’s five forces was first pubilshed in 1979 in the Harvard Business Review by a young associate professor at the Harvard Business School‚ Michael E. Porter. This article started a revolution in the strategy field and has since than shaped a generation of academic research and business practise. Throughout the last thirty years Porter’s Five Forces Analysis has been the

if a force with the same magnitude at opposite angles would equal to a net force of zero. If we equalize all the forces so we get a net gain force of 0 then no weight should touch the floor or the pulleys. We then tested if we added an extra weight with certain angle. We found out at what angle and what weight would equalize the force. The dependent variable is the force we used to equalize the force table. The controlled variables are the weight we initialized to create an unbalanced force. Equipment

http://www.physicsclassroom.com/mmedia/circmot/rcd.cfm What is ‘g force’ in physics? G‚ in physics‚ a symbol relating to gravity. A capital G indicates the gravitational constant‚ as explained in the article GRAVITATION. A lower-case g stands for the acceleration imparted by gravity at the earth’s surface. An acceleration of 1 g is 32. 1 feet per second per second (9.8 m/s2). Fliers and astronauts may experience accelerations many times larger than 1 g. These accelerations are usually expressed
