Linear and Angular Motion

The greater the applied impulse the greater the increase in velocity. Principle 4 – Linear Motion

Movement usually occurs in the direction opposite that of the applied force. Principle 5 – Linear Motion

A few more definitions Joint Range of Motion – Refers to the amount of movement present at a particular joint Streamlining – Refers to making an athlete or object as smooth a possible so that the flow or water or air past the athlete is smooth. When the lines of flow are parallel, the flow is said to be streamlined. This minimizes the surface area of the athlete.

And more… Force – A push or pull that causes motion Velocity – The rate of change of position (m/s) Acceleration – The rate of change of velocity

Angular motion is produced by the application of a force acting at some distance from an axis, that is, by torque. The application of torque produces changes in angular motion. Principle 6 – Angular Motion

Angular momentum is consistent when an athlete or object is free in the air. Once an athlete is airborne, he or she will travel with a constant angular motion. Principle 7 – Angular Motion

And more definitions Torque – the tendency of a body segment to rotate about its axis Angular velocity – Refers to how fast an athlete, body segment or object rotates about its axis Moment of Inertia – The measure of resistance to motion Angular Momentum – The quantity of angular motion
