Pendulum Warm Up
How does Newton’s First Law of Inertia describe the motion (or lack of motion) of the pendulum bob—right now?
Question One
How does Newton’s Second Law of Motion describe the motion of the pendulum bob when it is released?
Question Two
How does Newton’s Third Law of Motion (For every force there is an equal and opposite reaction force) help to describe the motionless pendulum bob as it sits now?
Question Three
If gravity accomplishes 12 J of work on the pendulum bob with 10 N of force, how far will the bob travel?
Question Four
If the bob travels 2 meters at a speed of 3 meters per second, how much time went by?
Question Five
What type of energy conversions occurred in this demo?
Question 3
Be ready for a quiz tomorrow!
