Pendulum
Transcript: pendulums- Definition,independent,dependent variable and controlled Expiriment- Pendulum by Brooklyn Gould Variable means-anything that you can change that might effect the outcome.Pendulum means-a mass that hangs from a fixed point that is free to swing back and forth.Cycle means-any kind of motion that is able to repeat itself.And,the standard pendulum system means-a regular pendulum that measures 38 cm. And swings from a 90 degree angle! Definitions,Variable,Pendulum,Cycle and the Standard pendulum systems- SCIENTIFIC METHOD- First find a question,then do some research and construct hypotheses. warning,you may have to try again and will become false so,go to construct hypotheses again then test with experiments.And lastly,analyze results-draw conclusion.Then,you may find if hypotheses is true or false! F.Y.I.,the longer the pendulum,the less amount of swings you get!But,the smaller the pendulum,the more swings you get! First,you will need a string, a paperclip,a ruler and some tape.Next,lay the ruler flat to the table then,attach the tape to the ruler and make sure it sticks!with the string,make a loop and put it through the ruler that extends from the table.And,tie the string to the paperclip and slide the penny through the bottom end of the paperclip! Independent variable means-a variable that stands alone and unchanged the one you know before the expiriment.Dependent variables means-a variable that depends on other ones and is changed, the one you know after the expiriment.And controlled expiriment means-An expiriment in which one and only one variable is changed.
