Basic physics states that if there are no external forces at work, an object will always travel in the straightest possible line. Accordingly, without an external force, two objects traveling along parallel paths will always remain parallel. They will never meet. But the fact is, they do meet...
What is the equation for calculating pure torque? The equation for pure torque is T = rF, where T is the torque, r is the distance from the axis of rotation to the point of application of the force, and F is the magnitude of the force applied. How is shear stress related to pure ...
The Monte Carlo simulation is used to model the probability of different outcomes in a process that cannot easily be predicted because of the potential for random variables.
Centripetal and centrifugal forces are two terms used to describe the physics of circular motion — but only one of them is real. The centripetal force keeps an object moving in a circle and is always pointed toward the center of that circle. For instance, the gravitational force of the sun...

Where this analogy breaks down, however, is that we cannot step outside the universe because there is no outside to step into. By definition, the universe is everything in existence, so nothing can exist outside it. That said, modern theories such as chaotic inflation, brane theory and ...
