| a push or pull action is called a? | force |
| what has both magnitude and direction? | vector |
| what describes the quantity of movement and not direction? | scalar |
| what science deals with time, space and mass? | kinematics |
| what science deals with bone movement? | osteokinematics |
| what science deals with joint movement? | arthrokinematics |
| the amount of matter in a body is called? | mass |
| what is the resistance to change of motion | inertia |
| the tendency of a force to produce rotation about an axis is called? | torque |
| the force developed by 2 surfaces tends to produce? | friction |
| if a vector describes the speed of movement you use _ _ _ _ _ _ _ _ to measure that movement | velocity |
| a object at rest tends to stay at reset is the law of? | inertia |
| the amount of acceleration depends on the strength of the force applied to an object is the law of? | acceleration |
| for every action there is an opposite and equal reaction is the law of? | action-reaction |
| a muscle is what kind of force? internal or external? | internal |
| a weight is what kind of force? an internal or external | external |
| two people push a box in the same direction what type of force is this called? linear, parallel or concurrent? | linear |
| two people are playing tug of war what type of force is this? linear, parallel or concurrent | parallel |

| part of the body in contact with a supporting surface is? | BOS |
| the imaginary line passing through the center of the COG | line of gravity |
| the great the friction the more _ _ _ _ _ _ an object is | stable |
| your balance will be better if you focus on a _ _ _ _ _ _ _ _ _ _ object rather than a _ _ _ _ _ _ | stationary moving |
