Experiment: Newton's Third Law
Questions:
Explain what caused the balloon to move in terms of Newton's Third Law.
What is the force pair in this experiment? Draw a Free Body Diagram (FBD) to represent the (unbalanced) forces on the balloon/straw combination.
Add some mass to the straw by taping some metal washers to the bottom and repeat the experiment. How does this change the motion of the assembly? How does this change the FBD?
If the recoil of the rifle has the same magnitude force on the shooter as the rifle has on the bullet, why does the shooter not fly backwards with a high velocity?
