PIRA classification 1C
1C30.10 |
free fall timer |
A ball is timed as it drops .5m, 1m, 1.5m, or 2m. |
1C30.16 |
dropping balls |
A ball is released by an electromagnet and a clock started. The catcher stops the clock and can be set at different heights. |
1C30.15 |
Free Fall Apparatus |
A table top free fall apparatus with push button sparker and using spark tape. Different weight can be used on the leading end of the tape. |
1C30.41 |
Falling Drops |
A strobe illuminates water dripping from a faucet at an uniform rate. |
1C30.46 |
"videostrobe" with falling drops |
Use the 60 Hz refresh rate of a video monitor to strobe falling drops by adjusting the rate to 60 Hz and having the stream fall past the screen. |
1C30.55 |
Catch a Meter Stick, Reaction time |
Drop a meter stick and have a student catch it. Distance can be converted to reaction time. |
1C30.55 |
Catch a Dollar, Reaction time |
Have a student try to catch a dollar starting with the fingers at the midpoint. |
1C30.55 |
reaction time falling meter stick |
Have a student catch a falling meter stick and relate the distance dropped to the reaction time. |
1C30.63 |
pendulum timed free fall |
A pendulum released from the side hits a ball dropped from the height that gives a fall time equal to a quarter period of the pendulum. |
1C30.66 |
many bounce method |
Time a bouncing ball for many bounces and determine g using the coefficient of restitution. |
1C10. Velocity
1C20. Uniform Acceleration
