Question

1. Compare the measured range to the calculated range.

2. Do the kinematics equations see to work in practice? If not, why?

3. Is it the fault of kinematics or due to some problems with the procedure?

Answer 1

1. The measured range is a bit smaller than the calculated range.
2. The kinematics equations work in practice, but with some error. The error is a result of ignoring air friction.
3. The problem is in procedure: if we conducted the experiment in a vacuum chamber, the theory and practice would go side by side (the results would be equal).
