Biomechanics Flashcards
Define motion
The continual change in position of a body relative to a particular point.
Define linear motion
Motion occurring in a straight line
Define angular motion
Motion which rotates around a fixed point
Define general motion
Motion which is a combination of both linear and angular
Define velocity of release
The faster the velocity of release increases the height and time in the air
Define angle of projection
The ideal angle is approximately 45 degrees
What is transfer of weight?
A weight transfer occurs when the dancer moves their weight from one body part to another.
What is a full transfer of weight?
A full weight transfer happens when the centre of gravity is vertically projected onto another body part, releasing the old body part to be moved again (e.g. walking).
What is a partial transfer of weight?
A partial transfer of weight happens when the centre of gravity is only partially projected to the new body part and the previous body part is unable to be freely lifted or moved.
Define summation of forces
Summation of forces is momentum transferred from one body part to another.
Define centre of gravity
The point through which the entire body may be considered to act.
Define base of support
The area of ground bounded by the points of the body in contact with the floor
Define balance
When the body is in a state of equilibrium, either when the body is at rest or whilst moving.
Define stability
The ability to maintain balance
