Learning Newton's Second Law

Learning Newton's Second Law Lab

Purpose:

In this activity you will be learning how to develop equations to relate force and mass to the acceleration of an object. 

Info

  1. You will be finding the acceleration of the object by finding the slope of the velocity time graph



  2. Force is measured in Newtons.

Procedure (Part 1):  Acceleration and Force

  1. Open the program found here.

  2. Do not change the mass of the hover puck for the entire first part of the this lab.

  3. Adjust your force to 8 different values and create a data table showing the force in Newtons and the acceleration in m/s/s.

  4. Create a graph of acceleration vs. force where force is on the x-axis and acceleration is on the y-axis.  If you are working on a device that doesn't support Logger Pro, use this graphing app.

  5. Make sure you transfer your graph, the equation for your graph and a description of the relationship you found into your lab book.

Procedure (Part 2):  Acceleration and Mass

  1. The best results for this part could probably be obtained by using a modest force (less than 2 N).

  2. Adjust your mass to 8 different values and create a data table showing the mass in grams and the acceleration in m/s/s.

  3. Create a graph of acceleration vs. mass where mass is on the x-axis and acceleration is on the y-axis.  If you are working on a device that doesn't support Logger Pro, use this graphing app.

  4. Make sure you transfer your graph, the equation for your graph and a description of the relationship you found into your lab book.

Procedure (Part 3):  Live Part

  1. Your teacher will be giving you further directions at this point on how you will be testing these relationships live.

Things to have in your lab book:

  • Purpose

  • Two data tables

  • Two graphs with all the things a good graph should contain.

  • Two equations that relates acceleration to the mass of the object and the force on the object.
