Civil Engineering
In engineering and physics, precision is not a luxury; it is a fundamental requirement. Whether designing a suspension bridge or a microchip, understa...
Based on the theoretical concepts, the current examples lacked coverage of:
To describe motion, we use a specific set of parameters. All of these (except time and distance) are vector quantities.
A force is intuitively defined as a push or a pull on an object resulting from its interaction with another object. Forces are vector quantities, mean...
In physics, "work" has a very specific meaning. It is the transfer of energy to or from an object via the application of force along a displacement.
Before analyzing collisions, it is helpful to define the center of mass (CM) velocity. For a system of particles, the CM moves with a constant velocit...
Just as linear kinematics describes motion along a line ($x, v, a$), angular kinematics describes rotation about a fixed axis ($\theta, \omega, \alpha...
An object is in static equilibrium if it is completely at rest in our chosen frame of reference. This means it has no linear acceleration and no angul...
Fluids differ from solids because they cannot sustain shear stress while at rest. They flow and take the shape of their container.
Any motion that repeats itself at regular intervals is called periodic or harmonic motion. The simplest and most important type is Simple Harmonic Mot...
In everyday language, "heat" and "temperature" are often used interchangeably. In physics, they have very precise and distinct meanings.
Matter is composed of atoms, which contain positively charged protons and negatively charged electrons. The fundamental unit of charge ($e$) is $1.602...
Historically, there was a great debate over whether light was a stream of particles or a wave. We now know that light exhibits properties of both, a c...
