The new serie « Physics Gets Physical », composed by 4 episodes of 12’ (2021) is now available on ARTE.tv replay up to june 27, 2026. Director: François-Philippe Gallois, Romain Blanc-Tailleur. Production: ARTE GEIE, FLAIR PRODUCTION with the participation of the CNRS and the Centre National du Cinéma et de l'Image Animée.
A serie to watch the Olympic Games from another point of view: from the Physics’one.

Pole vault, Sprint, Trampoline… in most of the Olympic disciplines, performances are contested within a few fractions of a second or within a few milimeters. Beyond intensive trainings, the athletes improve their performances thanks to the study of biomechanics and physics’ laws.

Pole Vaulting : Overcoming Gravity – The Strongest of Them all:  Energy is still a mysterious fundamental notion of physics. In this athletics  field, Jumps well illustrate this notion : the jumping action is based on the kinectic energy converted into elastic energy, before being converted in turn into  gravitational energy. This is a key property of energy. To reach a performance, pole-vaulters and jumpers athletes have to play with energy in order to optimize it, transforme it and keep it.

Sprinting and Newton’s Law – the Mechanics of Strengh: Running races champions, like planets or any kind of moving object, obey to Newton’s second law : Dynamics. The sprint sport practice gives us the opportunity to peel this law principles to understand why all is done according to the outset of th spint…. Ready, set, go !

The Trampoline and the Kinetic Energy:  If you launch a spinning top, it will spin by its own for a while. In this sport field, trampoline gymnasts can performe almost fifty rotations within 20 seconds, thanks to the Kinetic moment (angular momentum). Would you enjoy a little tour of the country of gynamsts ?

Windsurfing and Lift: have you ever seen a windsurfer cutting through the waves, by harnessing  the wind? As if she were flying over the sea? This is an amazing sport and this is possible thanks to a windsurf equiped with a « foil » (a centreboard), using a physics’ notion : Lift. This very notion that makes the planes glide and takes the javelins far away from the throwers. What if you feel your wings grow, without being Icarus ?

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
