If the force is outside of the midline, the direction of the movement is in the same or different direction?
Same
Impulse is caused by a change in _____________________ when impacting the ground
change in momentum when impacting the ground
What is a joint reaction force?
force generated within the joint in response to external forces acting upon it
Kinematics is the description of ______________
motion
Kinetics deals with the causes of ______________
motion (including force and torques)
When in midair, there is no __________ force from the ground, but _______________ is still acting on the body
no reaction force from the ground, but gravity still acts on the body
When landing, the vertical ground reaction force is at its ___________
peak
If not hit squarely, point of application will cause _______________
rotation
Linear forces are in a __________ direction
single
With a wider stance, there is a(n) _________________ in acceleration which _________________ force of med-lat ground forces
Increase in acceleration which increases the force of the med-lat forces
