Experiment #2: Acceleration vs. Mass Link https://phet.colorado.edu/sims/html/forces-and-motion-basics/latest/forces-and-motion-basics_en.html In this lab you will determine the relationship between acceleration and mass. Choose an Applied Force at the beginning, and keep it constant for this entire experiment. Set the friction to zero. This will make your Applied Force equal to the net force. Record data for five different values of Mass. Graph Acceleration vs. Mass. Graph this in Google sheets(you want a line graph - it should only have one line). Make sure that Mass information is used as the x value Make sure that Acceleration information is used as the y value Add a trendline – see what fits best – linear, exponential, polynomial, etc … Add a copy of you graph below the table Applied Force (N) Mass (kg) Acceleration (m/s²)
kihetic friction), f = µN. f is directed opposite to the relative velocity. Example 3.4 Block and Wedge with Friction A block of mass m rests on a fixed wedge of angle 6. The coefficient of friction is u. (For wooden blocks, u is typically in the range of 0.2 to 0.5.) Find the value of 6 at which the block starts to slide, and the acceleration X when it slides. In the absence of friction, the block would slide down the plane; hence the friction force f points up the plane.
