Free Fall and Pendulum Experiment
1.Master the theory and method of measuring acceleration of gravity by free fall.
2.Grasp the relationship between single pendulum vibration’s cycle and length.
3. Research on experiment of acceleration of gravity etc.
1.Steel base, equip with spirit level to monitor horizontal situation. Equipped with stainless steel solid.
2.Adjust the height by photogate timing device.
3.Single chip timing device can show the times in real-time to prevent mistake.
4.By photogate timing device, user can query, save, time and count, it can save 20 lines of data automatically by customer’s setting.
5. It can save presupposed periodicity, corresponding time and total time when the power cut
Photogate timing device
Length:1000mm,adjustable for pendulum length; Diameter: Φ18mm
Distance:1000mm ; Diameter: Φ10mm
The nine digital display, timing: 999.999999s,resolution: 1μs
0-999 can set automatically for 0-999 times, equip with highly sensitive photogate
Typical experimental context and data
1.Context of simple pendulum experiment
a) Fixed pendulum length, measuring the value of “g”
b) Change the pendulum length, count the period of simple pendulum by photogate timing
2.The method of measuring acceleration of gravity free fall
