All the tech we rely on, from cars to smartphones, was engineered using physics.You don’t need to know the science to use these things. But a well-rounded human should understand at least some ...

Haug’s newly-introduced maximum mass velocity equation seems to be fully consistent with application to the relativistic rocket equation and it gives an important new insight into the ultimate limit ...

Continuity Equation When a fluid is in motion, it must move in such a way that mass is conserved. To see how mass conservation places restrictions on the velocity field, consider the steady flow of ...

Some things to notice: This escape velocity depends on both the mass and the radius of a planet. Also, there is no direction in this expression. It doesn't matter which way you are moving to escape.
