Measurements and Standards
A quick introduction to the concept of units of measure.
- To give concept of primary and secondary standards, use aluminum block to 'calibrate' meter stick and calipers.
- Measurement of fundamental units and their standards.
- Length: Beyond common examples already shown, discuss use of monochromatic light as a standard reproducible anywhere.
- Time: From ordinary to atomic clock, i.e., show clock, pendulum, electronic oscillator, stable atomic clock.
- Mass: Explain gravitiational and inertial mass. Compare unknown to known masses on balance and obtain density of three red blocks and determine the material they are made of.
