Unit 3 Activity - Hooke's Law Name: Learning Goal I can describe and explain Hooke's Law. Success Criteria I can conduct a scientific inquiry to collect observations and data. I can draw conclusions based on the results obtained in a lab setting. Introduction One important type of potential energy is associated with springs and other elastic objects (rubber bands, bungie cords, etc.). You may be familiar with simple springs such as those seen in the diagram below. When no force is being exerted on the spring (a) it is said to be in resting state. However, when the spring is stretched (b) or compressed (c) then the spring exerts a reactive force that is equal and opposite in direction to the applied force. These reactive forces are also called restorative forces because it tends to restore the spring to its natural resting length. Stretched: Relaxed state: Faping = 0 Compressed: x is positive x is negative. Block is at x = 0. FX- x=0 = 0 (a) b (c Purpose The goal of this investigation is to determine the relationship between the force applied (F) to the spring and the displacement (4x) of the end of the spring. Method 1. Go to the following website to directly open the app we will be using for this investigation. https://phet.colorado.edu/sims/html/masses-and-springs/latest/masses-and-springs_en.html 2. Click on Lab on the far right of the menu. 3. On the right of the screen is a box for options. Set your options to match those in the image below. Displacement Natural Length Mass Equilibrium Movable Line Period Trace 4. Attach the 100g mass to the spring. Measure the displacement (Ax) by using the ruler tool and measuring between the natural length (blue dotted line) and the mass equilibrium (black dotted line). Record this value in the table below. Fit Page Width Unit 3 Activity - Hooke's Law Name: . Repeat Step 1 for a mass of 50g, 150g, 200g and 250g. You can change the mass of object using the slider just to the left of the spring. Record all values in the table below. Mass I 50 g 50 300 Results and Data Table Mass (kg) Ax (m) Fg (N) 0.050 0.100 0.150 0.200 0.250 Analysis 1. For each measurement in your table, calculate and record the force using the equation F=mg. 2. Create a graph of Fg vs Ax. Draw a line of best fit. (You can use a computer for this step if you want) 3. Calculate the slope of the line of best fine. What does this slope represent? 4. Write an equation for your spring in the form of F = kAx, where k is the slope of your line of best fit. 5. Describe in words the relationship between the force applied to a spring and the displacement of the spring
