1. Conclusion questions for toy car lab

2. What we “know” so far…
Motion is measured by the formula distance divided by time.
Distance divided by time = rate (speed)
Example: mph (miles PER hour)
Distance divided by time in a given direction is:
velocity (example mph eastward)
The rate at which velocity changes is acceleration.
Acceleration refers to increasing speed, decreasing speed, or changing direction.

Answer the following on a separate sheet of paper. (you will need a few sentences to explain…)
1. Did the outcome of your experiment support your prediction?
2. Were there any uncertainties or difficulties in the design of the experiment?
3. Can we really ever say whether an object is in motion? (think about what you know and what you have done so far)
4.How do you think that motion could be determined before stopwatches, timers, or spark timers were invented?
