 |
A projectile’s trajectory and
range is examined for various
launch angles.

Cavendish Experiment:
Gravitational interaction
observed and gravitational
constant determined.

Physics Demonstrations in Mechanics
is a four-part video series presenting a full range of demonstrations in linear motion, two-dimensional motion, Newton’s laws of motion, momentum, work & energy, and gravitation. Similar in format to
Demonstrations in
Mechanics Parts I & II, this more recent series (Parts III through VI) significantly broadens and enhances the collection of mechanics demonstrations. The program’s strength lies in the use of specialized apparatus, high-speed photography, and 3D computer animation.
|
Program Format
Individual demonstrations are 3 to 4 minutes in length and can be quickly accessed using the
program's on-screen indexing system. The indexing system allows the teacher to select a particular demonstration and show it at the appropriate time during a unit on
mechanics.
Demonstration Selection and Filming
Techniques
The selection of demonstrations includes those which are difficult to perform in the classroom and those requiring apparatus not readily accessible to many physics teachers. Detailed observation of the demonstrations is accomplished through use of a filming approach which focuses solely on the apparatus, allowing the teacher to utilize the program in a way which is consistent with his or her personal instructional approach. The voice over narration eliminates the on-screen presenter and allows attention to be directed to the physical behavior being studied.
