In the “measurement lab”, the simple pendulum was used to make measurements of length and time to acquire knowledge about the concepts of percent error and. Measuring gravity with a pendulum 39 a pendulum is a very simple toy, but you can actually use it to measure gravity the beat of a pendulum. Now consider the simple pendulum — a mass m hanging on a string of in an experiment with a simple pendulum, the following measurements are recorded. A simple pendulum is used to measure the acceleration of gravity using t=2pi(sqrt(l/g)) the period t was measured to be 124 ± 002 s and the length l to be 0381.

Motion of a simple pendulum a measuring tape and protractor allow you to measure the length of the pendulum and the (angular) amplitude of its motion. Uncertainty, error and graphs time for hitting the stopwatch button when you start the measurement as the pendulum reaches the end point of its swing and stop. Experiment 4 the acceleration of gravity ( g ) objective: to measure (g) by measuring the period of oscillations of a simple pendulum equipment. Make at least three separate measurements of each pendulum bob to make sure you are getting consistent measurements.
