biomechanical principals Flashcards
1
Q
define newtons 1st law of motion
A
law of inertia: an object will remain at rest until acted upon by a larger external force to overcome inertia
2
Q
define newton’s second law of motion
A
law of acceleration: the bodys rate of change of momentum is proportional to the size of the force applied and acts in the direction of the force, the greater the force the greater the accelaration however mass remains constant
3
Q
what is the equation for force
A
force = mass x acceleration
4
Q
define newtons 3rd law on motion
A
law or action and reaction: for every action there is an equal and opposite reaction
