First thing first, add a description to you lab notebook of our final one-second pendulum group experiment. -- We did a bunch of 10-second trials, each person adjusting the length of their pendulum to make it run faster or slower, until we found the spot where it swung with a one-second period, that length turned out to be 25 cm, or so? And then we quickly experimented to find a two-second pendulum, which was about 100 cm. Can anyone make a guess as to how long would be a 3-second pendulum? Leave a comment below.
For homework, read Chapter 2, section 1 in your textbook.
In your lab books, make a page for Energy and Motion Vocabulary, and find the meaning of these words as you read: [along with definitions, draw a little picture to illustrate the concepts]
distance
displacement
speed
average speed
instantaneous speed
velocity
what is the difference between distance and displacement
what is the difference between speed and velocity
what is the mathematical formula for finding speed?
