Pendulum+Activity+Simple

. __Pendulum Activity__ Copy figure 14 on page 362 and answer the question. Learn what concept figure 10 on page 386 is showing. A pendulum is a swinging mass hanging on a string. Height will be above the resting position of the mass hanging down. One swing of the pendulum is the mass swinging out from one side __and back__. In all the dimensions tested, the responding variable will be how long it takes to swing out and back. The first manipulated variable will be the release position of the pendulum measured at a height or angle. The second manipulated variable will be the amount of mass hanging on the string. The third manipulated variable will be the length of the string suspending the mass. Full Length/ Half Length/ Quarter Length Note: Swing time might be more accurately measured by timing five swings and dividing by five if the time is very short. Note: The release position of the pendulum can be measure as a height or angle. Think about: What proof do you have that objects with different masses fall at the same rate?

A pendulum can be used to figure out the force of gravity. []
