We can use the Hubble constant to make a first guess at the age of the universe simply using the equation: speed = distance divided by time. The Hubble constant tells us the speed of an object at any ...

An object moving in a circular orbit at a constant speed has a changing velocity. This is because velocity is a vector quantity that depends on speed and direction. The object in orbit is ...

A light year is a distance. It is the distance light travels in one year. As light travels at constant speed, the distance light travels in a year can be calculated using the equation: ...

It states that as the speed of the moving fluid increases ... and the kinetic energy of the fluid motion, remains constant. Bernoulli’s Equation formula is a relation between pressure, kinetic ...
