the blocks might not be the same size.

Discrepancies between measured values of different blocks could be due to factors such as variations in block composition, surface roughness, temperature, or the precision of measurement instruments. Additionally, human error during measurement or differences in measurement techniques could also contribute to discrepancies.
Discrepancies in measurements of identical features on fischertechniks blocks may be due to variations in measurement technique, human error in reading or recording measurements, differences in perception of what constitutes the feature being measured, or variations in the condition of the blocks themselves (e.g., wear and tear). It is important to standardize procedures and ensure accuracy when conducting measurements to minimize these discrepancies.
Not necessarily. Styrofoam blocks can have different densities depending on how they are manufactured or what they are made of. Densities can vary between different styrofoam blocks based on factors like the amount of air or other materials trapped inside the foam.
The tension between two blocks in a structural system is influenced by factors such as the weight and distribution of loads, the material properties of the blocks, the design of the connections between the blocks, and external forces acting on the system. These factors can lead to stress and strain within the blocks, causing tension between them.
The tension between two blocks being pulled in opposite directions is influenced by factors such as the force applied to each block, the friction between the blocks and the surface they are on, and the mass of the blocks. These factors can affect the balance of forces and determine the overall tension experienced between the blocks.
The blocks in Feynman's lecture on energy represent energy levels of different systems, where each block represents a different possible level of energy. By stacking the blocks, Feynman demonstrates how energy levels can change and how energy is transferred between systems. This visual aid helps to explain the concept of conservation of energy.
