On the rebound, the acceleration varies. The jumper is accelerating up but as the bungy recoils, the jumper starts accelerating down again due to the pull of gravity. This does not mean that he’s moving down, however, only that his velocity upwards is decreasing.
Congratulations, the acceleration of the bungy jump is greatest at the jumper’s lowest point. This is because the bungy is now stretched to its maximum, meaning if applies a force up on the jumper more than twice his weight. This means he accelerates up at a greater rate than the acceleration down when he left

How should we depict an atom? Like a solar system with electrons orbiting the nucleus on hula hoop orbits? That idea is so last century!

Whenever an object spins through the air it experiences a ‘Magnus Force’ due to friction between the air and the object’s surface. This force was originally identified while studying the trajectories of cannon balls (though earlier observations of this effect exist). The Magnus force is essential in most ball sports including golf, cricket, tennis, and
