Physical growth and maturation are an example of which type of constraint of Newell's model?

• 1. environmental  

• structural 

• functional

• Task

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

• 5. intensity and inertia 

• 4. optimal sequence and timing  

• 3. force production and inertia  

• 2. optimal sequence and intensity  

• 1. intensity and timing  

Which of the following are the two branches of the ecological perspective?  

• 1. maturational and information processing  

• 2. dynamic systems and perception-action  

• 3. maturational and dynamic systems  

• 4. perception-action and maturational  

• 5. information processing and dynamic systems 

The maturational perspective explains developmental change as a function of maturational processes, in particular through the development of the  

• 1. physical body  

• 2. muscular system  

• 4. central nervous system 

• 3. peripheral nervous system  

What does Newton's third law of motion state?  

• 1. Gravity is inversely proportional to force multiplied by mass.  

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

• 3. For every force you exert on an object, the object exerts an equal force back on you in the opposite direction (law of action-reaction).  

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

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.

• a rotation

• the interaction of contraints

• inertia

• an open kinetic chain

The observation that many children perform many of the same motor skills while demonstrating individual differences highlights which two concepts in motor development?  

• 1. motor development versus motor control  

• 3. individual versus structural constraints 

• 4. gross motor skills versus fine motor skills 

• 2. universality versus variability  

The perception-action approach uses which of the following terms?  

• phase shifts and products  

• body scaling and affordance  

• process and phase shifts  

• affordance and biomechanical description  

What does Newton's second law of motion state? 

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

• 2. For every force you exert on an object, the object exerts an equal force back on you in the opposite direction.  

• 3. Gravity is inversely proportional to force multiplied by mass.  

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