Hoop Lab Whiteboard Discussion

What is your vertical intercept sentence? ("When the [x-variable] is 0 [units], the [y-variable] will be...")

Does your vertical intercept value make physical sense? Is it close to zero? Close enough to call it zero? What are some reasons why it would/wouldn't be close enough?

What shape is your graph? (Linear/non-linear) What are some pieces of evidence that may support that your line isn't linear?

What are your units for the slope? (remember RISE over RUN) What property of the experiment (speed, mass, energy, volume, etc) could these units describe? (hint: another question had you simplify the units)

You have an odd set of units in your slope, which may help convert between velocity and energy, but the slope may be more helpful if you simplify the units. What would be that simplified unit?

Another question had you simplify your slope units and, hopefully, you found the unit for mass. What would this be a mass of? On the counter in the back, there is a balance. Can you measure the mass of this object you used in the lab and write it here? Compare this measurement to the value of your slope. Do they match? If not, is it close enough to match? OR, perhaps the slope has some factor difference than the object's mass. What is that factor?
