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

When we touch something that is hot or cold, what are we actually sensing? Is it the temperature of the object, or the rate at which heat flows between the object and our hand?
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

Raw interviews: http://www.youtube.com/watch?v=8dcw98B2Nzg The question has arisen often enough that I thought I’d answer it. If you hold views that are consistent with the majority of the population, does that make you stupid? I don’t think so. Science has uncovered a lot of counterintuitive things about the universe, so it’s unsurprising that non-scientists hold beliefs
