Journal of Rock Mechanics and Geotechnical Engineering
The dry hot rock core exhibits extensive transverse fractures, hindering its full extraction. This is closely related to the changes of rock physical and mechanical properties under high temperature and the development of fractures under high stress.
Energy of falling object
As an object falls from rest, its gravitational potential energy is converted to kinetic energy. Conservation of energy as a tool permits the calculation of the velocity just before it hits …
4 Signs Your Car Might Be Totaled After an Accident
Getting into a car accident can be a difficult experience. Luckily, your car insurance company will usually pay for any mechanical or auto body repairs caused by a covered accident. However, if the costs of repairs are more than the vehicle is worth, the insurer might declare it a total loss and give you the cash value instead.

Weathering and erosion (video) | Khan Academy
Water, a powerful force, shapes our world through weathering and erosion. Rain dislodges soil particles, leading to mechanical weathering. As water accumulates, it moves soil and rock particles, causing erosion. Fast-moving water erodes more than slow water, creating landscapes like meandering rivers and Oxbow lakes.
Weathering Rocks | Scientific American
Physical weathering (also called mechanical weathering) happens when physical forces repeatedly act on the rock. One example is rocks tumbling over one another, knocking off pieces from one another.

Herbert H. Einstein's group at the Massachusetts Institute of Technology conducts research in rock mechanics, engineering geology, and underground construction, spanning a wide range of studies from field measurements to laboratory experiments to numerical and analytical models.
2.7 Falling Objects
Falling objects form an interesting class of motion problems. For example, we can estimate the depth of a vertical mine shaft by dropping a rock into it and listening for the rock to hit the bottom. By applying the kinematics developed so far to falling objects, we can examine some interesting situations and learn much about gravity in the process.
