Force Formula

Force equals mass multiplied by acceleration (F = ma).

Stability

The ability to maintain a state of equilibrium where forces are balanced.

Angular Motion

Motion around a fixed axis or point.

Study Notes

Biomechanics Quiz

  • Force, Mass, and Acceleration are related: Force = Mass x Acceleration

Motion

  • The ability to control a state of equilibrium (equal forces) is Balance
  • An athlete completing a Golf Swing would be undertaking Angular Motion

Stability and Balance

  • Wide base of support when standing helps to Increase Balance and Stability
  • Static Stability refers to the ability to maintain equilibrium when stationary
  • Inertia is the tendency of an object to resist changes in its motion

Friction

  • Friction is a force that opposes motion between two surfaces in contact

Balance and Motion

  • Static Balance is the ability to maintain equilibrium when stationary
  • Example: A gymnast standing on a balance beam
  • Dynamic Balance is the ability to control equilibrium while moving
  • Example: A surfer riding a wave

Newton's Laws of Motion

  • Newton's First Law of Motion: An object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force
  • Example: A hockey player gliding on ice without external forces
  • Newton's Second Law of Motion: The acceleration of an object is directly proportional to the force applied and inversely proportional to its mass
  • Example: A tennis player hitting a ball with a racket
  • Newton's Third Law of Motion: For every action, there is an equal and opposite reaction
  • Example: A swimmer pushing against the water to propel themselves forward
