Lifespan Motor Development Chapter 3 Quiz

An individual's _______________ is the ability to resist movement or disruption. For example, individuals are essential to participating in the sports of powerlifting and golf

Stability

What does Newton's second law of motion state?

The acceleration of a person or object is proportional to the force applied to it and inversely proportional to its mass

What does Newton's third law of motion state?

The law of action-reaction states that for every force you exert on an object, the object exerts an equal force back on you in the opposite direction.

What does Newton's first law of motion state?

You must apply force to a stationary object to move it and to a moving object to change its movement.

Motion and stability are affected tremendously by the interaction of ______________.

constraints

To improve and optimize movement performance, individuals must find the optimal relationship between __________ and __________ in a given movement.

force; distance

_________ refers to an object's resistance to motion and is related to the mass of an object.

inertia

A key point of this chapter is that ____________ principles govern all of our movements

mechanical

In a maximal ballistic effort (such as kicking a ball as hard as possible), the movement involves multiple body parts that act in a sequence. This sequence is knows as a(n):

open kinetic chain

Which of the following are elements of the open kinetic chain of movement?
