Biomechanics Flashcards
Biomechanics
Analyse and understand how forces affect movement and how to apply biomechanical principles to improve movement skills physical activity, sport and exercise.
Force
Defined as a push of pull. It can produce movement or change the motion of an object.
Mass
The amount of matter that makes up an object.
Acceleration
The rate of change in velocity (speed).
Velocity
Speed of an object in a given direction.
Weight
The force that is exerted on an object or a body by gravity.
Gravitational force
The force of attraction between two bodies or objects.
Friction
A force that acts in the opposite direction to motion when two surfaces are in contact with one another. Less friction means higher velocity.
Torgue
The turning effect produced by a force.
Angular Motion
Movement of a body part around an axis of rotation. Involves the rotation around a central axis or a fixed point.
Eccentric Force
A force that does not act through an objects centre of gravity.
Momentum
The amount of motion an object has and its resistance to changing that motion.
Conservation of Momentum
Water Resistance
Air Resistance
Inertia
Summation of Momentum
