Which of the following is not a type of motion? A. Translatory B. Rotary C. Perpendicular D. Curvilinear |
|
Definition
C. Perpendicular is not a type of movement
A. Translatory is where all the points on a segment travel in a parallel line
B. Rotary is where a segment travels through an arc of motion around a single axis of rotation
D. Curvilinear is a combination of rotary and translatory motions (reaching for a cup and moving it to mouth) |

1. Sagittal
2. Frontal
3. Transverse |
|
|
Term
What are the three axes of motion that correspond to the x axis, z axis and y axis? |
|
Definition
1. Medial - Lateral motion is in the x axis
2. Anterior - Posterior motion is in the z axis
3. Superior - Inferior motion is in the y axis |

Mass vs. Weight. What is the difference? |
|
Definition
Mass is the amount of matter composing the object
Weight is the force acting on the object due to gravity and is the product of the objects mass and acceleration due to gravity (g = 9.8m/s^2) |

Term
What is Newton's first law? |
|
Definition
An object remains at rest or continues moving at a constant velocity unless acted upon by an unbalanced external force (law of inertia) |
|
|
Term
What is Newton's second law? |
|
Definition
If there is an unbalanced force acting on an object, it produces an acceleration in the direction as and directly proportional to the force (F=ma) |
|
|
Term
What is Newton's third law? |
|
Definition
For every action (force) there is an equal and opposite reaction |
|
|
Term
Work vs Power. What is the difference? |
|
Definition
Work is the force required to move an object a certain distance (work = force x distance)
Power = the rate that work is being done (power = work/time) |
