Biomechanicak Movement Flashcards
Mass
Quantity of matter the body possess
Weight
Gravitational force exerted on an object
Displacement
Shortest route from starting point to end point
Velocity
Rate of change of displacement
Acceleration equation
Change in velocity Over time
Momentum equation
Mass x velocity
Vertical forces
Weight
Gravity
Horizontal forces
Friction
Air resistance
What does weight do as a verticals force
Gravitational force
Greater the mass of individuals the greater the weight force pulling them downwards
Mass x acceleration
What is reaction force as at vertical force
2 bodies are in contact with one another
How do Frictional forces act as horizontal forces
Static - force exerted one one surface by another when there’s no motion
Causes sliding friction
Friction resists the slipping or sliding motion of 2 surfaces
What can friction be affected by
Surface characteristics
Temperature of surfaces
Mass of objects
What does air resistance depend upon
Velocity of the moving body
Cross sectional area of the body
Shape and surface characteristics
Impulse definition and equation
Time it takes a force to be applied to an object or body
Force x time
Angular displacement define
The smallest change in angle between the start and the finish point of rotation
Measured in degrees and radian
