Picture the arch. It resists the pull of gravity. The force of gravity is a constant, and it wants to pull the center of the span down. But the materials distribute some of the force sideways. The sides of the arch support much of the weight of the structure, but they have to be designed to resist being "pushed apart" by the arch as well as to hold it up. Take two sticks and a smooth table top. Stand the sticks a little apart and tip them to where the tops touch. Put just a bit of tape there to keep the sticks touching and pushing on each other. With a smooth table and a goodly space between the bottoms of the sticks, the sticks will slip sideways and fail to stand up. That's the "down" force of gravity acting along the stick. It pushes down, and the sticks resist. And some of the force is vectored "along" the stick and causes an "outward" push. It's an experiment that shows the "down and outward" force on the sticks, and the arch experiences similar forces. There are some other considerations that must be looked at in arch construction, but those two are the primary ones. It is the "down" and the "out" forces that are greatest in the arch. Links are provided to relevant Wikipedia posts. One is to a nice drawing, and the second is to the article on the arch. If pictures are worth a thousand words, there is a book here. And there are arches that have been standing for a thousand years, too!

What is the driving force behind the principles of physics?
The driving force behind the principles of physics is the pursuit of understanding and explaining the fundamental laws that govern the behavior of the universe. Physics seeks to uncover the underlying principles that govern the interactions of matter and energy, and to use this knowledge to predict and explain the behavior of physical systems.
What is the secret behind the physics hand trick that seems to defy gravity?
The secret behind the physics hand trick that seems to defy gravity is the manipulation of forces and balance. By positioning your fingers and hand in a specific way, you can create the illusion that an object is floating or defying gravity. This trick relies on the principles of physics, such as center of mass and equilibrium, to create the optical illusion.
What is the physics behind fidget spinners and how does it contribute to their spinning motion?
Fidget spinners spin due to the conservation of angular momentum. When you flick the spinner, you give it angular momentum, which is then conserved as the spinner spins. The physics behind this involves the distribution of mass in the spinner and the friction in the bearings, which allows the spinner to keep spinning for a longer time.
What is the physics behind the water bottle flip?
The physics behind the water bottle flip involves the conservation of angular momentum and the center of mass of the bottle. When the bottle is flipped, it rotates around its center of mass, and the angular momentum is conserved as it flips in the air. The goal is to land the bottle upright by controlling the rotation and speed of the flip.
How do physicians use physics?
Physicians use physics principles to understand medical imaging techniques like X-rays, MRI, and ultrasound. They also apply physics concepts when prescribing treatments involving radiation therapy, surgery, and medical devices. Understanding the physics behind these technologies helps physicians make accurate diagnoses and provide effective treatments.

Is arch a erosion or a deposition?
An arch is typically a result of erosional processes, where softer rock is eroded away, leaving behind harder rock that forms an arch-like structure. It is not typically associated with deposition.

What is the name for a column of rock left behind after an arch collapses?
A column of rock left behind after an arch collapses is called a "hoodoo." Hoodoos are tall, thin spires of rock that form in arid regions through the erosion of surrounding rock.
What is the physics of a toaster?
Physics is simply the study of the properties of matter and energy. The physics behind a toaster is that the toaster conducts electricity to produce heat, toasting bread or whatever other food.
