displacement, do you see a linear relationship? What does the slope of this graph represent? Yes, I do see a linear relationship, the slope represent the spring constant, every spring is characterized the spring constant. Looking at the graph you made of force vs. We kept the distance from the cart and the photogate to a sufficient distance, which was around 20 cm, this was done in order for the error to be reduced in the velocity, if distance was too close then ratio of two small numbers will result in large error. measuring the velocity to so that we can find the change in kinetic so where should you place the photogate to measure the velocity?briefly explain your reasoning.

Source of Errors: source of error for this lab was that when we let go the cart the cart would hit the sensor really hard due to it being really fast and that affected our data and result in us having a big percent error. Precautions: order to do this lab, we can make sure to let the cart go on the track smoothly and touch the sensors smoothly in order to get sufficient data and sufficient percent error. Calculate the average power for your data oatined. Test the theorem for the cart spring system and do calculations Compare the work done on the cart these forces to change the kinetic energy of the cart calculating the percent difference. Insert a graph into capstone and choose force to be on the and the distance to be on the Interpret the graph as need to find the area and points. Hit record in the capstone when you let go the cart and record the final and initial velocity. Pull the cart back until there is enough tension in the spring to move the cart but not so much that the spring is overextended. Set up the capstone system as mentioned in the manual. Procedure: Part 1 2: Set up the motion sensor force sensor and the photogate sensor as shown in figure blow: The motion sensor should be atleast 20cm away from the phogate For part1, 2 photogates will be needed and for part 2 only one photogate will be needed. One of the goals of this lab was to understand how force do work on the cart in order to change its kinetic energy, another goal was to find the work done changing force using integration, and lastly understand the understand and find power that was exerted a Apparatus: lab should already provide us with the cart with the flag, track and two photogates, motion sensor, stand with a rod and clamp, force sensor,balance, spring, balance, Computer with a system that has pasco interface and capstone software.
