-
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.
- Gravity (FG):
- 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
Compressive Force
-
Type of force that tends to elongate an object
Tensile Force –
-
Type of force that causes an object or surface toslide over another.
