So of the four fundamental sources of forces (no, not Yoda's force), which two do we usually work with in the lab? (and no, the sun doesn't count ;-)
This week we'll be looking at the effects of combining the effects of Gravitational force and Electromagnetic forces - things that make us balance or accelerate. (Newton's first Law!)
Now that you've pushed my car around, what can we say about the relationship between Force, mass, and acceleration?
And since that data wasn't as precise as we might like, we want you to set up experiments to collect better data.
Equipment can include (but isn't limited to) WDSS, tracks, carts, masses, cart photogate(s), cart picket fences, string, etc. etc. etc.
YOUR FOCUS IS ON COLLECTING EVIDENCE (data, pictures, video, etc.) TO SUPPORT YOUR CLAIM about how FORCE, MASS, and ACCELERATION are related...
Have someone in your group start up a google doc and share it to your group and teacher, call it something like CONSTANT FORCE, and start filling it with evidence :-)
We'll worry about what to turn in later after we've done some more things, just take lots of pictures and collect good data to support your claim(s)!
P.S. What evidence do we have that the Earth is hot in the middle? Why is it hot?
P.P.S. Why do all things fall with the same acceleration (if we ignore air resistance)?
