ICE PRINCESS
I am delighted
to share my watching movie experience which I found it was interesting yet
inspiring. This movie inspire me in the journey to reach dream .Ice Princess
was the movie that had steel my heart and force my eye to keep on watching it.
Ice Princess movie
start with Casey Carlyle, a very smart and talented science student ,plans to
pursue a scholarship to Harvard University. Casey must present a personal
summer project about physics for the scholarship. While she was watching a
figure skating competition with her friend , Ann she realizes that ice skating
, would make a perfect project.
She improve her
skating by applying physics and watching it from other skaters.Later she
becomes proficient and skips two levels to become a junior skater. She helps a
junior skater named Gen and other friends improving their skating. Torn between
her Harvard dream and her growing love of skating, Casey has difficulty
juggling schoolwork, skating and a part-time job. Casey’s mother attempts to
prevent Casey from skating due to her declining academic performance.At the
same time, a tension occurs between Casey’s coach and Gen’s mother.
The climax of the
story was when during a competition ,Casey’s coach, Tina Harwood sees that
Casey may outrank Gen,and she attempts to sabotage Casey’s performance by
switching her skates.I would like to suggest you watch this movie because I may
not going to proceed writing the synopsis and my intention here is to share my
discoveries from the movie.To be honest, the movie had strengthen my physic
knowledge on the law of conservation of angular momentum.
1)How many of us understand the properties of physics that
allow skaters to glide over the ice, jump,
and spin?
2)What is the reason that skaters can turn at full speed and
not fly over the rink’s barrier when they come to the end of the rink?
This can easily be done by the skater if they have the
ability to control their core body ,so they instinctive can balance over their
skate.
“In an isolated
system, with no external forces, the law of conservation of momentum states
that the momentum is conserved. The law of conservation of angular momentum
states that the angular momentum in an isolated system, with no external
torques, will be conserved.”
First,we measures the amount of spinning motion using
angular momentum.
- The higher the amount of angular momentum of a spinning object, the faster it is spinning.
- The amount of mass and the distance of the mass from the axis of rotation influence the number of rotations per second or known as the rate of speed.
- The length of time a skater can hold a spin depends on the skater’s ability to centre the spin.
If they lose their centre of balance, the spin will start to
wobble and her centre will shift.
Then, we use the moment of inertia as the rotational
analogy to mass.
- The moment of inertia is calculated by the mass and the distance of the mass is from the axis of rotation.
- By increasing the mass or the distance of the mass is from the rotational axis ,the moment of inertia also increases.
Next, figure skater change her moment of inertia by
controlling how close her centre of mass is to the axis of rotation.
- By extending the arms and one leg, the figure skater can increase the moment of inertia in a spin.In contrast, by pulling the arms and legs to body, a decrease in the moment of inertia happens.
- To slow a spin, a skater need to extend both arms away from the core body.The moment of inertia increases, and so the angular velocity correspondingly decreases.
Lastly, in
performing a jump,
- A skater make an adjustment in the distance of the arms from the center of the body axis, so the skater can fine the tune of the moment of inertia and the angular velocity.This principle allows the figure skater to theoretically adjust the number of turns that will be precisely made in the air prior to landing the jump
What value I get
from this movie is we must always
practice in order to get a perfect result.In order to reach our goals , we need
to keep on trying even life is getting harder and tougher. Always bear in mind
that nothing is really over until the moment we stop trying. We need to have a positive
mind and see the problems as the way to improve ourselves and later become the
best of all, just what Thomas Edition says, “I have not failed. I’ve just found
10,000 ways that won’t work”.
Thank you for your time reading my posts.
