Hooke's Law #1

Error bars are too small. Best fit line does not pass though second and third data points. Second point is farthest away. It's error bars need to be about three times bigger

Voltage Across a Capacitor

Best fit line appears to pass though all the data points. The best fit line is grazing the edge of several error bars, so the error bars are about the right size.

Electron Beam in a Magnetic Field

Error bars are too small. Best fit line does not pass though the first data point. It's error bars need to be about twice as big.

Transformation of Energy

Error bars are too large. Best fit line passes though data points not just within error bars. Error bars need to be about five times smaller.

Pressure of a Gas

Error bars are are about right. Best fit line does pass though all data points. Second point is farthest away from best fit line. It's error bars could be a bit smaller but not enough to worry about.

Uniform Straight Line Motion

Error bars are too big. Best fit line does pass through all the data points. The fifth point is farthest away. It's error bars could easily be half their current size.

Friction

Error bars are too small. Best fit line does not pass through all the error bars. The fifth point is farthest away. It's error bars need to be about five times larger.
