Physics - Chemical PhysicsPhysics - Fluid DynamicsA spreadsheet algorithm is given for the atomic force microscope that accounts for non-linear behavior in the deflection of the cantilever and in the photo-diode response. In addition, the data analysis algorithm takes into account cantilever tilt, ...
force is a concept rooted in physics, where is has a very specific and critical meaning. The standard unit of force is the newton (N), equal to kg ⋅ m/s2.
In normal life, time is a tool we use to measure the procession of events of space. But time is something more. Yes, we use time as a "tool", but time is essential for our physical existence. Space and time when used to describe events can't be clearly separated. Therefore, space ...
We measure it in units of cycles (waves) per second, or hertz. The frequency of visible light is referred to as color, and ranges from 430 trillion hertz, seen as red, to 750 trillion hertz, seen as violet. Again, the full range of frequencies extends beyond the visible portion, from...
You can measure magnetic fields using instruments like gauss meters, and you can describe and explain them using numerous equations. Here are some of the basics: Magnetic lines of force, or flux, are measured in Webers (Wb). In electromagnetic systems, the flux relates to the current. A fie...
Measure the mass (or weight) of the liquid with some scales and convert to kilograms. Measure the volume of the liquid with a measuring jug and convert to m3. Divide the mass by the volume. You will then have the density of the liquid in units of kg/m3. Which planet has the lowest...

In the USA, torque is often expressed in foot pounds (ft/lbs). To convert N⋅m to ft/lbs, simply divide the N⋅m value by 1.356. Petty Officer 2nd Class James R. Evans inspects the drive shaft of a helicopter rear rotor U.S. Navy Why do we need to measure torque? Measuring...
Mass and weight are proportional to each other and are often used interchangeably in the everyday world. But while mass is proportional to weight, they are not the same. Calculating mass gives a measure of "matter" or "stuff," whereas weight is the force
So how do we measure this? To determine the acceleration you experience in a corner, all we need is the radius of the corner and your speed. I measured the radius of a normal right turn at an intersection of two four-lane roads and found it to be about 17 metres. This means that ...
