A spring and mass oscillating.
 

 

 

 

 


A spring and mass oscillating, showing the transformation of energy from potential to kinetic and back again, and again, and again, ...
 

 

 

 

 


Here's a simple ball rolling in the bottom of a cylinder. For small angles, it acts like a SHO.
 

 

 

 

 


A simple pendulum animated.
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 


A coin rotating showing the direction of the static friction force.
 

 

 

 

 


A simplified version of earth in its orbit, showing the direction of the gravity force vector.
 

 

 

 

 


A tennis ball being swung around on a string. Here we see the tension force pointing towards the center.
 

 

 

 

 


The centripetal acceleration vector of a pawn on a rotating record player.
 

 

 

 

 


A model of air particles in a tube creating a standing wave. (Inspired by Daniel Russell.)

"I end up making a lot of animations and images for my intro physics lectures. Here are some which I'd like to share with those in need of such materials."

These animations and much more are available at Dr. Hedberg's website
