Most of the athletes have put in years of intense, focused physical and psychological training. For those who will be watching them, or who play sports themselves, we have created a virtual special issue called The Physics of Sports.

The articles here are freely available until October 31, Understanding the physics of motion can affect all areas of sports, from helping athletes move faster, to preventing injuries, planning more efficient trainings, and developing aerodynamic equipment and clothing. Physics and sports are intimately connected. Work and energy are among the most important concepts of physics.

Both, work and energy, play an important role in sports. In physics, work is defined as the result of a force moving an object a certain distance. Thus, force and work are directly proportional to each other. In addition, the concepts of work and energy are closely related. Hence, work transfers energy from one place to another or one form to another. During a pole vaulting performed by athletes, different types of energy are involved. First, the athletes transform chemical energy into kinetic energy of their body while running.

Part of this kinetic energy becomes elastic potential energy, as observed by the deformation of the pole; the rest of energy becomes gravitational potential energy, which again it is transformed into kinetic energy while the athletes fall away from the bar. In physics, if a system is isolated from its surroundings, that is, if no external forces acting on it, there are three conserved quantities which means they maintain the same level or energy or transform into other types of energy : energy, linear momentum and angular momentum.

In classical mechanics, conservation of linear momentum the product of the mass and velocity of an object is implied by Newton's laws. Angular momentum — also known as rotational momentum — is the quantity of rotational motion a body has. It is the product of the moment of inertia i. Conservation of angular momentum is another important concept.

For example, consider a figure skater who turns on the tip of her skates. In the absence of external forces, the angular momentum is almost constant.

When a figure skater draws her arms and a leg inward, she reduces the distance between the axis of rotation and some of her mass, therefore reducing the moment of inertia and her friction with the air. Since angular momentum is conserved, her rotational velocity must increase to compensate. The force of friction is the force resisting the displacement of one surface over another and material elements sliding against each other. In all sports, friction represents a braking force that needs to be overcome; the more you can overcome this force, the better your chances of success.

Using the example of skating, Dr. Skating is possible because the melted liquid layer in-between ice and skate has macroscopic thickness. It is due to the heat generated by friction. We show that such a lubricating melted water layer always exists for standard values of ice skating data, contrary to what happens in the case of cavitation of droplets due to thermal heating Leidenfrost effect.

During the last 10 years, Dr. Le Berre has collaborated with Prof. Yves Pomeau of the University of Arizona on topics ranging from the quantum tunnel effect in fibers, to earthquake predictions, supernovae description, ice-skating, the study of irreversible phenoma like turbulent flows, and recently the fluorescent emission of a single atom.

Recently they published an article on ice-skating:. Swimmers suffer the gravity and the force of water in swimming. Achieve efficient movement through such dense as water environment is one of the biggest challenges they have in common coaches and swimmers.

Those who can move through the water while minimizing the effects of physical forces on their bodies are guaranteed to get excellent results. Swimmers must find ways of how to improve their position or arrow streamline and simultaneously reduce the area occupied by their body as it moves through the water.

By reducing the area, they reduce resistance, which acts as opposing force in the water — very similar to the friction out of the water. Aerodynamics is a term of physics that describes the ability of an object to overcome air resistance. Thus, it can be applied to cycling, the bicycle composition and design, the clothing worn by the cyclist, and even the positioning of the rider on the bicycle.

He explained:. Coatings are currently used to extend the lifetime and enhance the performance of several components that are used by athletes. For example, coatings are used to reduce friction improve on the wear resistance of bearings used in high performance bicycle bearings.

Finally, epoxy coatings are used on kayaks and on paddles to enhance their scratch and corrosion protection. In addition, aerodynamics plays a big role in all ball sports related. The air flow around a ball thrown through the air differs greatly depending on whether it has a smooth surface or a rough surface. Hugh Trenchard, an independent researcher in Victoria, British Columbia, Canada, whose interest in peloton dynamics and collective behavior stems from his experiences as a competitive cyclist, runner and duathlete.

His primary research objective is to show how self-organized principles of peloton dynamics are ubiquitous across biological collectives and represent fundamental principles of evolution. During the Tour of France, spectators might wonder why cyclists spend most of the race in pelotons. Cyclists can travel significantly faster by traveling in pelotons and by drafting i. The shorter is the distance between cyclists, the larger is the decrease in wind resistance.

Also, cyclists save more energy if they are among a group of eight cyclists than if they are drafting behind just one or two other cyclists. Therefore, aerodynamics plays an important role in cycling races.

When cyclists save energy by drafting, they also couple their energy expenditures. This interactivity produces self-organized collective behavior.

Of course top-down behavior does occur in pelotons, and cyclists constantly adjust positions according to team tactics and strategies. However, certain collective behaviors can be shown to emerge from underlying physical coupling principles. The study of collective behavior is an area of physics known as complexity theory, and includes the study of flocks, schools, and herds. With these three factors, we can model the collective behavior of pelotons.

We can show that there are different thresholds and phases of collective behavior. A phase transition means there is both a quantitative and qualitative difference in the pattern formation and structure of the peloton. Such phases include cyclists forming a single-file line, when they are cycling near their sustainable maximums and cannot easily pass others; and a dense and compact formation, when riders cycle at lower outputs and can pass their neighbors.

Thus, drafting is used to reduce wind resistance and it is seen in cycling, running, swimming, and car racing as well. Drafting and physiological factors produce collective behavior and phase transitions. Computational Fluid Dynamics is a computational technique used to model drafting that can help athletes to prepare and train more efficiently.

In these articles, the authors apply principles of applied mathematics used in medical settings to measure biological signals, detect fatigue and achieve more healthy trainings.

The use of an alternate system to make transporting such items from the check-in area to the aircraft easier is at the discretion of company staff. The passenger will bear any costs that may arise from transporting the equipment. Special equipment carried on board is classified as a piece of hand luggage.

Space puts all materials under severe stresses, allowing only the most robust products to survive. Testing materials for space is crucial to ensuring the devices that use them will last in the worst conditions known to humanity without a repair service anywhere in sight. Without testing, the efforts of putting satellites into orbit are for naught when the devices fail in the heat of the atmosphere or the cold of space.
