a new understanding of fluid-rock deformation
... where the mechanism for deformation is fluid movement by flow or dispersion along pressure gradients between neighbouring grain-boundary cracks in crystalline rocks, and aligned pores and pore-throats in sedimentary rocks, at different orientations to the stress field (Zatsepin & Crampin, 1997; Cram ...

... When sky divers reach terminal velocity they are traveling at a constant speed. The forces of gravity accelerating the skydiver towards earth are matched exactly by the force of friction from the air particles pushing against the skydiver. If the person wears a more aerodynamic suit or points their ...

... Ans: Tremors on the earth can be caused when a volcano erupts, or a meteor hits the earth, or an underground nuclear explosion is carried out. However, most earthquakes are caused by the movement of earth’s tectonic plates. Q. What is the scale used to measure magnitude of the intensity of earthquak ...
Friction
... Here µ is a unit-less scalar that is called the coefficient of friction (COF). In the above figure we can easily see that by Newton’s second law, the normal force must be equal to the objects weight, thus the force due to friction depends on the COF and how much the top object is pressing down on th ...

... Water waves, sound waves, and the waves that travel down a rope or spring are types of mechanical waves. Mechanical waves require a medium, such as water, air, ropes, or a spring. Because many other waves cannot be directly observed, mechanical waves can serve as models. The two disturbances shown i ...
