In our universe, a Constant is a value that remains constant throughout space and throughout time. The Gravitational Constant, G, for example – so far as we can tell – remains regardless of when or where the measurement takes place. So too…
read more“An electric charge is the property of matter where it has more or fewer electrons than protons in its atoms. Electrons carry a negative charge and protons carry a positive charge. Matter is positively charged if it contains more protons than electrons,…
read moreThe Metric Tensor in General Relativity is a Set of 10 parameters ascribed to each point in space, the values of which describe the geometry of spacetime. Metric means “measure,” and a tensor is simply the higher dimensional analogue of vector, i.e….
read moreIt is notable that time dilation is not limited to kinetic or gravitational time dilation, but by virtue of the unification of gravitation and acceleration by the Equivalence Principle of General Relativity, by acceleration as well. In all cases, Time Dilation is…
read moreOn the surface, the concept of Time Dilation seems so strange to us that we imagine its formula must be one of incredible complexity. In reality, its incredible simplicity almost belies the genius required to conceive of it (Minkowski, Lorentz, Einstein). It…
read moreA derivative is the instantaneous rate of a change of a variable with respect to another variable. For example, Velocity is the rate of change – or derivative – of an object with respect to time. When we say a plane is…
read moreJerk is the third derivative of position with respect to time .
read moreAverage Velocity is calculated using the change in displacement over a period of time. The change in displacement is calculated as the initial displacement subtracted from the final displacement, that quantity divided by the initial time subtracted from the final time.
