When I first read “Much madness is divinest sense”, I most definitely missed some of the incredible universal themes that it speaks to. It actually reminded me of a story I was introduced to recently about some new technology in the energy field. Apparently, a …
The physics concepts that were illustrated in our egg drop project were momentum and energy. In the project, we saw how momentum increases as a normal egg without anything to slow it down would crack. That was because the longer that the egg fell, the …
The objective of this lab was to understand how to use the Working Model 2D software and to apply this knowledge to create a vibration absorber. Part 1 was to open up a demo file and analyze the force vs. time of the piston. Part …
Magnitude
In physics, magnitude is described in simple words as 'distance or quantity'. It shows the direction or size that is absolute or relative in which an object moves in the sense of motion. It is used to describe the size or extent of something. Generally, in physics, magnitude relates to distance or quantity.
Equilibrium
equilibrium, in physics, the condition of a system when neither its state of motion nor its internal energy state tends to change with time.
