Kiss the Egg

Catalog: 
1R10.101
Location: 
Ae4

First students determine the spring constant for a conical spring. Then they compute the height at which a mass, attached to the spring, can be released and fall just “kissing” the egg below without it breaking.

Walking the Spool (Advanced version)

Catalog: 
1K10.30B
Location: 
Ac3
This demo consist of a track and 3 spools. Spool 1 has a 1:2 axle to wheel ratio, spool 2 has a 2:1 axle to wheel ratio, and spool 3 has a 1:1 axle to wheel ratio.

Laded Beam (Instructor version)

Catalog: 
1J40.40E
Location: 
A plank is supported by a bathroom scale at each end. The instructor then walks along the plank while having students note the force measured by the scales.

1Q10.32
Location: 
Ad4
A ring and disk with the same diameter, width, and approximately the same mass are rolled down an incline.

Maxwell's Top

Tracer spiral of Maxwell's top
Catalog: 
1Q50.90
Location: 
Ae5
This gyro, very similar to the one designed by Prof. Maxwell, is designed to show that a gyroscope will always react at 90 degrees to an applied force. To show this the spindle of the heavy spinning wheel, which is pivoted at it's center of gravity, will follow an irregularly shaped object (in this case a Tracer Spiral).

1 Newton Apples

Catalog: 
1G10.301
Location: 
Ab3
These apples weigh 1N due to the force of earth's gravity.
