Forces during Tim Peake's launch to the International Space Station
Issue 363 | Page 25 | Published Dec 2016
Despite the advanced technology and engineering that has gone onto the International Space Station and other space programmes, the measurement of the force experienced in the spacecraft is tested using a method that is well over 350 years old. The time of oscillation of a simple pendulum, as often investigated in school physics, provides the basis for comparing the forces experienced by astronauts with the force of gravity we experience on Earth and recognise as'weight'.
