Two demonstrators sit at either end of a rotating platform and toss a ball back and forth. When viewed from the rest frame (when the camera is mounted to the ground), the ball follow a straight line but doesn't reach its target because ...

A ripple tank is placed above a mirror and a projection screen. A horizontal bar, whose frequency can be varied, taps the surface of the water and produces plane waves. The waves are incident on a barrier containing an adjustable openi...

A ripple tank is placed above a mirror and a projection screen. Two synchronous point sources, whose frequency can be varied, tap the surface of the water and produce circular waves. The interference pattern of the waves including the li...

A long beaded chain is looped over a motor pulley. When the motor is turned on, a disturbance in the chain causes waves to propagate through it. When the motor is brought up to full speed and the chain is knocked off the pulley it will...

A wire frame is dipped in bubble solution and placed in front of a speaker. At certain frequencies, the soap film oscillates in symmetrical patterns called normal modes. A light is reflected off the soap film through a lens onto the wall...

A cart moving at constant velocity shoots a ball straight upwards. Since the ball has the same translational velocity as the cart, it is caught when it comes back down.

Subatomic particles such as cosmic ray muons, alpha particles, and high energy electrons are striking our bodies all the time. In the cloud chamber, these particles ionize air molecules, creating delicate cloud trails by condensing supe...

Two pucks of the same mass are slid at each other on an air table, and their resulting collisions demonstrate conservation of momentum. Notice on the first collision, for example, that when a moving puck hits a stationary puck dead-on, ...

Odd-shaped objects with their centers of mass marked by orange paint are thrown. While the objects appear to follow very wobbly trajectories when viewed under bright lights, under black lights you can see that their centers of mass trave...

Two or more air carts are connected by springs on an air track. When this system is at resonant frequency, symmetrical patterns called normal modes appear. The normal modes are shown in both undriven and driven cases. In the undriven ...

A laser is directed at an adjustable single slit and then a pinhole and the resulting diffraction patterns can be seen on a screen. A laser directed at two slits spaced closely next to each other creates an interference pattern within...
