General Motion Flashcards
a angle formed by a body segment with respect to horizontal is
absolute angle
if all factors are held constant what would the effect choking up on a bat have on a resultant linear velocity of a hit ball
decrease
if angular acceleration is constant, then angular velocity is
increasing or decreasing
the compound of angular acceleration directed toward the center of the curvature defines
radial acceleration
angular velocity units
rad/s
if the angular velocity of a batters shoulder increases,what will happen to the linear velocity of the end of the bat
linear velocity increases
what is instant center
the center of rotation for a joint at any given point in time
counterclockwise
positive angle
what describes angular velocity
change in angular position over a given time
angular displacement / time
what is angular displacement in body
range of motion at a joint
goniometer
can measure human body angles
used by physio
radial acceleration
object rotating in a circular path is a componenet of linear acceleration directed towards axis of rotation.
centripetal force is a force exerted on an object to cause radial acceleration
a quadruple axel(in firgure skating) involves how much angular diplacement
0 degrees
