1D10. Displacement in Two Dimensions
PIRA # |
Demonstration Name |
Abstract |
1D10.20 |
Cycloid Generator |
A large spool with a light bulb fastened to the circumference is rolled along the table. With and without the lights on. |
1D10.30 |
Inversor |
A mechanical device that transforms rotational motion into rectilinear motion. |
1D10.40 |
Mounted Wheel |
A bicycle wheel marked with a radial line turns about its axis. |
1D10.55 |
Projected circular motion |
A Turn table with a ball that rotates with an arrow on top is projected on a screen by a arc lamp. |
1D10.60 |
measuring angular velocity |
Use an electronic strobe to measure the angular velocity of a fan blade or other rotating objects. |
1D15. Velocity, Position, and Acceleration
PIRA # |
Demonstration Name |
Abstract |
1D15.10 |
ultrasonic detector and students |
Have a student walk toward and away from a sonic ranger while observing plots of position, velocity, and acceleration on a projection of the Mac. |
1D15.15 |
kick a moving ball |
Kick a moving soccer ball on the floor or hit a moving croquet ball on the lecture bench with a mallet. |
1D15.20 |
high road low road |
Two objects start at the same velocity, one moves straight to the finish, the other traverses a valley. The problem: which wins? |
1D15.30 |
catching the train |
A ball accelerating down an incline catches and passes a ball moving at constant velocity on a horizontal track. |
1D15.35 |
passing the train |
A ball accelerates down an incline with a stripped rope moving at constant velocity in the background. The moment the ball has the same velocity as the rope is strikingly obvious. Repeat with the rope at a different constant velocity. |
1D15.40 |
Galileo's circle |
Several rods are mounted as cords of a large circle with one end of each rod top center. Beads released simultaneously at the top all reach the ends the rods at the same time. |
1D15.45 |
brachistochrone track |
Three tracks - straight line, parabola, and cycloid are mounted together. Triggers at each end control a timer. Details. |
