1. Investigating Newton’s Second Law Lab

2. result in a loss of points!!!
Please sit in your same groups from the last lab. Take out your pre-lab assessment. Touching materials before being instructed
to do so will
result in a loss of points!!!

3. Look at step #5. Decide within your group which one of the two scenarios you will do:

4. Two Scenarios – acceleration is always the dependent variable!!!
acceleration vs. mass: The independent variable is the mass and the control is the force
acceleration vs. Fnet: Be careful not to change the total mass of your system! The independent variable is the force and the control is the mass
