Energy of a Pendulum

Page history last edited by Mr.Schayer 14 years, 5 months ago

Experiment with a virtual pendulum by clicking on this link: 

pendulum lab

 

 Answer these questions on your worksheet:

 

 What happens to the speed of the pendulum when there is lots of friction?

 

What happens to the speed of the pendulum when there is no friction? 

 

(Experiment by adjusting the friction knob)

 

  

Now, make the following adjustments to answer questions about energy:

  •  Show energy of 1
  •  Switch from Real Time to 1/16 Time to slow down the animation
  •  Make sure there is no friction

 

  

What happens to potential energy when the pendulum is at its highest height (on either side)?

 

What happens to potential energy when the pendulum is at its lowest height (in the middle)?

 

  

What happens to kinetic energy when the pendulum is at its highest height?

 

What happens to kinetic energy when the pendulum is at its lowest height?

  

What do you notice about the total energy of the pendulum?
