Name: SPH3U1 PhET FRICTION LAB Sum of Forces 7 values Masses speed Answer these Pre-Lab Questions: lone Friction . What is the formula for FG (weight)? Define the following three terms: . FN-Normal Force: Applied Force . EnKinetic Friction: 0 Newtons Fis-Static Friction: LAB Forces and Motion: Basics . Go to the following URL: https://phet.colorado.edu/sims/html/forces-and-motion-basics/latest/forces-and= Motion motion-basics en.html Frelion SELECT FRICTION Net Force Objective: In class, we've discussed, diagrammed and calculated different types of forces. The goal of this lab is to understand the relationship between frictional force & normal force, to determine frictional forces on an object based on computer simulations, as well as solve for unknown forces and masses using the equations learned in the class. Forces Select the following settings, DO NOT MOVE THE FRICTION SLIDER.>> >> >> > > > > > > > > > > > > > > > > Sum of Forces Values Play with it for a few moments to familiarize yourself with the controls. With the settings in place _ Masses complete the following chart by manipulating the simulation. Apply a FORCE to the objects until Speed THEY JUST BEGIN TO MOVE! Use the following equations: Friction F= U Fn Fg = mg Object(s) Mass Weight Normal Force Applied Force Static Friction Coefficient of Friction Trash Can Man Refrigerator 2x Crates 1. What has to happen before the Applied Force begins to move the box? 2. What happens once you exceed the frictional forces? 3. Explain what happens to the box once you stop applying force
