Gravitational Potential Energy for Extended Objects01:07

Gravitational Potential Energy for Extended Objects

1.9K
Consider a system comprising several point masses. The coordinates of the center of mass for this system can be expressed as the summation of the product of each mass and its position vector divided by the total mass:

Newton's Law of Gravitation01:15

Newton's Law of Gravitation

16.7K
Our everyday observation tells us that all objects close to the Earth naturally tend to fall to the ground. Early philosophers assumed that this downward force was unique to Earth. By the 16th century, Nicolaus Copernicus (1473-1543) put forward the heliocentric theory, which suggested that Earth and other planets orbited the sun, while the Moon orbited the Earth. However, it was Isaac Newton (1642-1727) who linked these two motions together in the 17th century. He reasoned that the force of...

Circles

156
A circle in the coordinate plane is defined as the set of all points that lie at a constant distance, known as the radius, from a fixed point called the center. This relationship is captured using the distance formula. For a point (x, y) on the circle and a center (h, k), the distance between them equals the radius r. By squaring both sides of the distance formula, the equation of the circle is written in standard form:Constructing the Equation from Geometric InformationIf the center and the...

Newton's Second Law00:55

Newton's Second Law

37.9K
Newton's second law is closely related to his first law of motion. It mathematically gives the cause-and-effect relationship between force and changes in motion. Newton's second law is quantitative and is used extensively to calculate what happens in situations involving a force. All external forces acting on a system add together to produce a net force Fnet. A larger net external force produces a larger acceleration. This acceleration is directly proportional to, and in the same...

Calculations of Electric Potential I01:15

Calculations of Electric Potential I

2.5K
Consider a ring of radius R with a uniform charge density λ. What will the electric potential be at point M, which is located on the axis of the ring at a distance x from the center of the ring?
The ring is divided into infinitesimal small arcs such that point M is equidistant from all the arcs. Here, the cylindrical coordinate system is used to calculate the electric potential at point M. A general element of the arc between angles θ and θ + dθ is of the length Rdθ and has a charge of...

Distance Measurements by Taping01:18

Distance Measurements by Taping

392
Tapes are essential in surveying for accurate, durable, and short-distance measurements. Made from lightweight, nylon-coated steel, they offer flexibility and strength for rugged outdoor use. The nylon coating protects against rust and wear, extending the tape's life. Standard lengths, around 30 meters, are marked in meters and millimeters for precision.Surveyors select tapes based on site conditions and accuracy needs. Lightweight, nylon-coated tapes are commonly used for ease of handling and...

    Area of Science:

    • Optical physics
    • Nanotechnology
    • Metrology

    Background:

    • Whispering gallery mode resonators (WGMRs) are sensitive to external perturbations.
    • Accurate distance measurement is crucial for calibrating WGMRs.
    • Previous methods using monochromatic light suffered from ambiguity.

    Purpose of the Study:

    • To develop a more precise and unambiguous method for distance calibration.
    • To improve upon existing interferometric techniques for WGMRs.
    • To achieve nanometer-level distance accuracy.

    Main Methods:

    • Utilized a trapezoidal prism coupler with a disc-shaped calcium fluoride (CaF2) WGMR.
    • Employed red-green-blue (RGB) illumination and captured color images of Newton's rings.
    • Applied phase extraction from Newton's rings in color images for distance measurement.

    Main Results:

    • Achieved distance measurement with an error of a few nanometers using a single image.
    • Improved accuracy to less than a tenth of a nanometer by incorporating a position reference.
    • Demonstrated elimination of the need for filters and enhanced precision.

    Conclusions:

    • The RGB Newton's rings method offers unambiguous and high-precision distance calibration for WGMRs.
    • This technique significantly advances WGMR characterization and sensor applications.
    • The method provides a robust and efficient approach for nanometer-scale metrology.
