<> Newton's Laws of Motion

       The mechanical principles of physics form a valuable tool to develop optimum sports techniques. However, there are many interpretations on how to apply the physics principles to a training program and effective teaching methods.

Principles from the Law of Inertia -
       Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
  • Achieving skilled movements requires the effectively combination of linear and angular motion. For example, the hooking action of the edge/turn to convert the linear motion into an angular motion that establishes the spin's center.
  • Two or more motions must be executed continuously in sequence. For example, in a jump the skater must spring into the air, complete the require number of revolutions, and check the rotation to achieve a controlled landing on the correct edge.
  • There must be a balance of mass and/or velocity between partners and members of a synchro team. For example, each individual must alter their direction and force to stabilize their combined movements or centrifugal force will become uncontrollable.
  • Control momentum efficiently for each body part to coordinate the entire body as a single unit. For example, changing positions from upright/layback to camel and/or sit spin positions.
Principles from the Law of Acceleration
       Acceleration is a very important ability for a figure skater to possess.
  • Acceleration/velocity is proportional to the force applied against the ice.  A skater who can increase his/her force applied to the ice increases their acceleration by an equal amount.
  • The maximum acceleration is achieved when all body forces are coordinated to achieve thrust in either the forward or backward direction.  Body actions that do not contribute to the forward or backward motion should be minimized to prevent wasted energy and/or detract from productive creation of power.
  • Lengthening the radius of our arms and/or free leg slows the body rotation; shortening the radius increases rotation. For example, a skater will achieve their maximum spinning rotation when they pull in their arms and free leg tight to the body. A came; spin can never approach the speed achieved in a scratch spin because the radius is longer in a camel spin.
  • A skater establishes the path in the air at take off.  The axis of the core body may wobble or tilt on its axis. which can adversely affects the skater's ability to complete the rotation in a vertical position, and land the jump on one foot in a controlled position.
The Principles of Counterforce
       A stable surface maximizes the potential counterforce that can be generated when force is applied against it. The less stable the surface, the less counterforce is generated. For example, a skidded edge does not produce the same spring force into the air for the skater as if a clean takeoff had been achieved.  The friction of the skid absorbs energy that is not transferred into the force that propels the skater into the air.
  • To achieve maximum jumping height, it is necessary to push directly down upon take off. The direction of counterforce is directly opposite that of the applied force, and the applied force is most effective when it is perpendicular to the supporting surface because skidding the edge is minimized.
  • Maximization of total force. The combination of thrusting from the jump foot and the free leg kick in the axel produce the total force into the air.

How to use Universal Laws & Principles To Your Advantage  A Universal Law or Principle is a general truth or rule that applies to all things anywhere they might be that is binding on anything that exist and are factors and parameters governing all creation.

Physics and Problem Solving  This lesson begins with a discussion of the law of inertia (a body at rest remains at rest and a body in uniform motion continues moving uniformly unless acted on by a net force). Next, the law of inertia is applied to a specific context, the use of seat belts and airbags in automobiles.

The Laws of Acceleration  Presented is a theory in fundamental theoretical physics that establishes the relationships between time, velocity, and the rate of acceleration for all material objects.  When properly formulated as given in this work, these relationships establish what appear to be two new natural laws of physics.  These laws, to be referred to as the Law of constant acceleration, and the Law of relative acceleration are in complete conformance with the principles of both, the time and energy theory, and the millennium theory of relativity.

Newton's Laws for Kids - 2nd Law   A Simple Explanation of Principles of Motion, Force, & Acceleration  Newton's first law tells us that a force is required to accelerate an object. Newton's second law answers the question about how much force is required.
