A force is a push or a pull. For example, when you push open a door you must apply a force to the door. You also must apply a force to pull open a drawer. You cannot see a force but often you can ...
Jul 31, 2024 · Pressure definition. Our pressure calculator uses the straightforward pressure formula below: p = F / A, where: p – Pressure; F – Force; and. A – Area of the surface. This pressure definition relates to the force applied perpendicularly to the object's surface. It would help if you remembered that pressure is a scalar, and therefore it ...

Key points. Pressure is a measure of how concentrated (or spread out) a force is. The amount of pressure exerted on an object depends on the force applied and the surface area it is spread over ...
Jul 2, 2024 · Protons, quarks, and the strong force. Physical Sciences. July 2, 2024. Quarks make up much of the matter around us and are bound together by the strong force. Probing the mechanical properties of quarks and the strong force is hard as the gravitational force needed is comparatively much weaker. Using Deeply Virtual Compton Scattering (DVCS ...

From way up here, it's tempting to think of the proton as a single particle. A hard shell of positive charge and mass, able to bounce and knock around as easily as a billiard ball. But in reality, a proton is made of three smaller particles. These particles have the delightfully quirky name of quarks. There are a total of six kinds of quarks in nat...
In the 1950s and '60s, physicists began to realize that the proton is not fundamental — it can be broken down into smaller parts. So they did a bunch of experiments and developed a bunch of theories to crack that particular nut. And they immediately ran into a) the existence of quarks and b) the puzzling conundrums above. Something was holding thos...
Imagine taking two little pliers and grabbing two of the quarks in the proton. You work out, so you are able to overcome the strength of the strong nuclear force holding them together. But here's something weird about the strong force: It doesn't diminish with distance. Other forces, like gravity and electromagnetism, do. But the strong force stays...

Pressure is defined as the force divided by the area perpendicular to the force over which the force is applied, or. P = F A. 11.7. A given force can have a significantly different effect depending on the area over which the force is exerted, as shown in Figure 11.5. The SI unit for pressure is the pascal, where.
