Biomechanics

Question 1

Kinematics

Answer 1

Analysis of human motion in relation to location and
direction of movement, the magnitude and velocity
of motion, and the type of motion occurring

Question 2

Newton’s 3 laws of Motion

Answer 2

1st: Inertia

2nd: Acceleration
3rd: Reaction

Question 3

Newtons 1st law of inertia

Answer 3

A body at rest remains at rest, a body

in motion stays in motion

Question 4

Newton’s 2nd law of acceleration

Answer 4

Force acting on a body creates
acceleration in the direction of the
force

Question 5

Newton’s 3rd law of reaction

Answer 5

For every action there is an equal and

opposite reaction

Question 6

Answer 7

perpendicular

Question 8
