What is The study of the action of forces on particles and mechanical systems; a branch of physics?
what is the Application of the principles of mechanics to the study of living organisms (e.g.,the human body and its parts) called?
Science which describes and predicts the
conditions of rest or motion of biological
systems under the action of forces.The application of mechanical physics to
what is The study of motion with special
reference to describing patterns of movement
and the speed of movement for the body and/or the limbs called?
name the planes:
what is The study of the forces acting on or produced by the body called?
whats the other name and definition?
The is the study of designing equipment and devices that fit the human body, its movements, and its cognitive abilities..
what is the name of the body position lying down face up in the anatomical position?
What is the name of the body position when the body is face down lying down in the anatomical position?
Toward the midline.
Away from the midline
Toward the head.
towards the feet
Closer to the trunk.
–Away from the trunk.
Front of the body
Back of the body.
What are the 3 axes of motion called?
vertical or longitudinal
what is the name of the axes of motion that passes from side to side at right angles to the sagittal plane (e.g., back flip).
What is the name of the axes of motion that passes horizontally from front to rear lying at right angles to the frontal plane (e.g., cart wheel).
What is the name of the axes of motion that passes from head to foot at right angles to the transverse plane (e.g., twisting).
Vertical, or Longitudinal
These are diagrams used to show the relative magnitudeand direction of all forces acting upon an object in agiven situation.
Resistance of humans moving through the air.FD α (velocity)2
Aerodynamic Drag (FD):
Aerodynamic Drag (FD): three rakings
< 12 MPH; FD is small (negligible).
12‐18 MPH; FD is moderate.
≥ 18 MPH; FD is high.
Refers to resisting the gravitational attraction between the Earth andyour body.
FG α Total mass in system
Static Friction (FST)
Resistance between two objects to NOT slide
FST must be great enough to hold two objects together.
Rolling Friction (FR)
Resistance to an object rolling over a surface.
FR is often a function of movement speed – Thus, faster rollingobjects experience more FR. This force is usually very small.
Normal Force (FN):
The force applied by the ground upward to the body in response to FG.
FN α FG
Applied Force (FA):
Refers to a force applied to an object by the body. This is considereddifferent from gravitational force which accounts for the body“pushing” on the ground.
E.g., Leaning on a wall – FA applied to the wall.
E.g., Vertical jump – FA applied to ground, which is in addition to FG.
Propulsive Force (FP):
This is the net force, or the resultant force vector,
Type of force that brings to surfaces orobjects directly together
Type of force that tends to elongate an object
Tensile Force –
Type of force that causes an object or surface toslide over another.
