Two athletes sq. off for an intense dance battle. The DJ begins spinning tunes, and the athletes start twisting, spinning and seemingly defying gravity, respectfully watching one another and taking turns exhibiting off their talent.

The athletes converse by way of their actions, talking by way of a dance that celebrates each athleticism and creativity. Whereas the athletes most likely aren’t consciously interested by the physics behind their actions, these complicated and mesmerizing dances exhibit a wide range of totally different scientific rules.

Breaking, also referred to as breakdancing, originated within the late Seventieswithin the New York Metropolis borough of the Bronx. Debuting as an Olympic sport within the 2024 Summer time Olympics, breaking will showcase its dynamic strikes on a world stage. This city dance model combines hip-hop tradition, acrobatic strikes and expressive footwork.

Since its inception, breaking has developed right into a aggressive artwork type. An MC narrates the actions, whereas a DJ mixes songs to create a dynamic ambiance. The Olympics will function two occasions: one for males, referred to as B-boys, and one for girls, referred to as B-girls. In these occasions, athletes will face off in dance battles.

Athletes earn factors for creativity, persona, approach, selection, performativity and musicality. Success on this sport requires combining dance strikes from three primary classes: prime rock, down rock and freeze.

Standing strikes

Prime rock strikes are carried out whereas standing up, specializing in fancy footwork and hand actions. These actions are harking back to hip-hop dancing.

Prime rock strikes depend on having numerous friction between an athlete’s footwear and the ground. Friction is the drive that resists once you slide one thing throughout a floor.

This friction permits the athlete to take very fast steps and to cease abruptly. The dancers should intuitively perceive inertia, or the truth that their our bodies will proceed within the path they’re shifting except they’re acted upon by an exterior drive. To cease abruptly, athletes want to interact their muscle groups, getting their footwear to grip the bottom to cease themselves from persevering with ahead.

Ground strikes

Down rock strikes are carried out whereas on the ground. Athletes might spin in circles with their head, again, elbows or shoulders touching the bottom and their toes within the air. B-boys and B-girls rely closely on an inner information of physics to finish these strikes.

Think about the physics of a backspin. A backspin happens when the athlete is on their again with their toes lifted within the air, rotating round a selected space of their again.

Sitting on the ground, the athlete’s left foot stays involved with the ground whereas they unfold their proper leg large, gathering linear momentum as they sweep their proper leg towards their left foot in a large arc. Then, they launch their left leg from contact with the bottom and roll onto their again.

Now that solely their again is involved with the bottom, the linear momentum from their leg turns into angular momentum, which rotates the athlete round an axis that extends upward from their again’s contact level with the bottom. This transfer turns magical once they deliver their legs and arms inward, towards the axis of rotation. This principal is known as conservation of angular momentum.

When an athlete brings their mass in additional carefully to the axis of rotation, the athlete’s rotations pace up. Extending their legs and arms as soon as once more and shifting their mass away from the axis of rotation will trigger the competitor to sluggish their rotation pace down. As soon as they decelerate, they will transition to a different transfer.

Stopping in a pose

Freeze happens when athletes come to a cease in a cool pose, usually occurring in time to the music and in an upside-down place. To freeze successfully, the athlete will need to have full management over their middle of mass, inserting it proper above the purpose of their physique that’s involved with the ground. The middle of mass is the common place of all of the elements of an athlete, weighted in line with their plenty. The “balance point” the place your entire mass of the athlete appears to be concentrated is the middle of mass.

Athletes are most secure when their middle of mass is as near the bottom as doable. You will notice many opponents freeze with arms bent in an effort to decrease their middle of mass. This lowered middle of mass reduces their distance from the ground and minimizes the tendency of their physique to rock to 1 facet or the opposite resulting from torque.

Torque is a twisting drive, just like the drive used to show a wrench. The torque will depend on two issues: the quantity of drive you apply, and the way removed from the pivot level you apply the drive. With an athlete’s middle of mass nearer to the bottom, the athlete decreases the gap between the pivot level – the bottom – and the place the drive of gravity is utilized – the athlete’s middle of mass.

Athletes want nice power to halt their movement mid-movement as a result of they’ve to use a drive to withstand the change in inertia.

Discovering the proper outfit

Many sports activities require a selected uniform. Breaking doesn’t – an athlete can put on no matter they need – however the proper outfit will maximize their probability of success.

The athlete desires a shirt that minimizes the friction between their physique and the bottom throughout a spin. Lettering or pictures on the again of the shirt will add friction, which hinders an athlete’s capacity to carry out some down rock strikes. An athlete might select to put on lengthy sleeves in the event that they plan to slip on their elbows, as naked pores and skin involved with the ground supplies extra friction.

Athletes even have to consider the headgear they put on. Whereas there are various totally different types of hats made particularly for breaking, the athlete will get to decide on whichever suits their dancing model greatest. They should be sure that their hat supplies some padding for his or her head whereas minimizing the friction between their head and the ground.

The again, elbow and head are axes of rotation throughout down rock, so the athlete desires gear that minimizes friction in any respect these locations. However additionally they want to ensure their footwear have grip to maximise friction whereas they’re doing prime rock footwork. Athletes additionally need to be sure that their arms aren’t sweaty or slick to allow them to use friction from their arms to manage how briskly they’re rotating throughout down rock spins.

On the planet of breaking – the place dancers appear to defy gravity – power and artistry work hand in hand with physics to create the strikes that can captivate audiences throughout the 2024 Olympics.
