Hitting the Sun is HARD
This video is about the orbital mechanics of why it's so hard to crash into the sun - the energy it takes to get there is astoundingly high, compared with leaving the solar system.

IB Physics Fields: Escape Speed
Field lines, potentials, equipotential lines and potential gradients – they sound similar but mean different things! With all these confusing terms, it would be much easier to kick back and watch some soccer (football). In fact, why...
