Escape velocity is part of the HSC Physics Syllabus Module 5: Advanced Mechanics.
There are many applications of gravitational force & energy in outer space. In this post, we will derive quantitatively and apply the concepts of gravitational force and gravitational potential energy in radial gravitational fields to a variety of situations.
Escape velocity
This is the velocity at which an object orbiting around the earth will “escape” its orbit. This happens when the potential energy is equal to the kinetic energy.
KE = \frac{1}{2} mv^2 GPE = -G\frac{M m}{r}Learn more about this concept in the video below:
