### Derivative Wikipedia

The derivative of a function of a real variable measures the sensitivity to change of the function value (output value) with respect to a change in its argument (input value). Derivatives are a fundamental tool of calculus. For example, the derivative of the position of a moving object with respect to time is the object's velocity: this measures how quickly the position of the object changes

### Jeans instability Wikipedia

An alternative, arguably even simpler, derivation can be found using energy considerations. In the interstellar cloud, two opposing forces are at work. The gas pressure, caused by the thermal movement of the atoms or molecules comprising the cloud, tries to make the cloud expand, whereas gravitation tries to make the cloud collapse. The Jeans mass is the critical mass where both forces are in

### Calculating Critical Speed A Motor-Vehicle Crash

Critical speed used in this context is a term for the speed at which a vehicle will lose lateral control on a given roadway curve. The normally flawed procedure is to assume the highway curve radius as the critical path taken by the vehicle. On the surface, this procedure appears reasonable since the driver is apparently attempting to drive around the roadway curve. This theory fails, however
