pendiulm effects
Laboratory topic # 10
In this experiment we will observe the properties of a pendulum moving in a circular motion rather than the traditional “back and forth” motion. This will simulate the direction that a satellite would follow above the earths atmosphere. The purpose of this experminate will be to show how gravity pulls on the string and the path that the pendulum follows.
Apparatus used:
1. Pendulum with long string 4. Digital stop watch
2. pendulum clamp 5. two-meter stick

…showed last 75 words of 305 total…just remember that you must make 1 complete turn before stateing that it is one turn.
Data:
Average radius of pendulum arc – 30.5cm (Converted to Meters - .0153m)
Length of pendulum string( to the top of bob) - 161.8cm Bob diameter – 2.5cm
Pendulum length to center of bob - 163.05cm Angle of string from vertical – 5.38°
Time for 4 reveolutions = 10.57 seconds. Average period = 2.643seconds.
Average speed 2.376 m/sec. (15.25/1000 = .0153m*.364m/sec = 2.376 m/sec.)
Am= .865 m/sec Ap = .923
% difference = {(am – Ap)/Ap} * 100% = -6.28%
