Demonstration: The higher the viscosity of a liquid the more it resists motion of a body through it. The result can be very...
Class practical: An object falling through water reaches a constant terminal velocity after falling relatively small distances...
This episode starts by considering the forces acting on a falling body in air, and moves on to related experimental work.
In the standing bottle, gravity pulls on the water so it presses on the bottom and sides and escapes through the hole. When...
The terminal velocity of a skydiver in the spread-eagled position is around 220 km/hr and, in the head-down position, 320 km...
