Newton's laws of motion

Challenge #27 in the Sevens series. Hosted by Dutch Newchurch.

Challenge has finished

This is the third in the series: ‘Seven Scientific Theories’. Imagine you have been asked to provide one or two creative and inspirational illustrations for a textbook, on Newton's laws of motion. A spacecraft in free fall (the first law)? A dragster burning rubber (the second law)? A heeling yacht (the third law)? An interceptor with flaming afterburners (the second or third law)? A cannon firing (the third or second law)? (The whole series is here: https://www.dpreview.com/forums/thread/4236850 )

Helicopter Rotors

by BBrooks

10^th place

low

high

A classic helicopter's motion is controlled by the forces of two rotors. Upward and linear motion mainly by the main rotor, while the tail rotor controls rotation allowed due to reaction to the main rotor torque. The versatility of the helicopters flight is due to the continuously variable combination of it's rotor's motion.
