Why can skiers be so far and so high that they are unharmed?

Science explains why these ski athletes can land safely on a hard snow surface from the height of a building without any damage.

Ski Jumping is a sport not for the weak hearted audience. Because just watching athletes compete, many of you will be stunned.

The process of the competition takes place full of danger: the athlete starts by sliding extremely fast down the long slope.

Why is this long and high jump like that athlete unharmed?

After that, they slid up a gentle sloping ramp, then took the momentum to 'throw' themselves into the air and did not forget to perform a series of rounds. In the end, they landed with both skis, continuing to travel short distances before stopping easily!

But do you wonder why this athlete is "landing" normally without any injury?

Professor Greg Gbur from the University of North Carolina explained: 'In fact, the athlete does not throw himself up and down vertically. If you think about jumping, as well as throwing anything into space, they will all fall in parabolic trajectories '.

Collages of athletes' movements in parabolic trajectories.

It is important that when landing, the athlete must control the skateboard along the slope to move into a parabola.

An athlete landed on the successful slope at.

This is also not easy because the body is under the influence of vertical gravity.

Suppose if the athlete falls straight from the top, the hard snow will stop any movement immediately.

Such sudden deceleration will cause an uneven effect on the body and break it into pieces.

However, this will not happen as long as the athlete slides down slowly along the designed slope.

This helps to reduce the speed, limiting the impact on the athlete's body until they can stop.

Ski Jumping at the Olympics is only for men.

After nearly 90 years, women have only competed in this competition since the 2014 Olympics.

Currently the highest record holder is Stefan Kraft - male Austrian athlete. He has recorded a 'flying' achievement as far as 253.5 meters in 2017.
