Is force a vector or a scalar?

A vector :)

What is the equation for impulse?

Force x time

All surfaces produce a _____________ force

Reaction force

Linear forces don't have ______________

Rotation

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
