Kinematics is:
Analysis of motion in terms of acting forces
Description of movement without reference to force/mass
Description of bodies at equilibrium
A kind of static force system
Which of the following is a description of a concurrent force system?
Forces acting along the same line
2 or more equal but opposite forces that cause rotation
Forces acting in the same plane, but along different lines
Forces acting at a common point, but in divergent directions
Flexion of the elbow is a biological example of what lever class?

Label the lever class:
Your client LOVES diet coke but since her injury does not have the strength required to open pop bottles. She has identified "being able to independently open a bottle cap on a coke bottle" as her most important goal. You decide to design an adaptive device that will help her with that task. What design would be the most helpful to her?
A socket type device that fits over the cap with a long handle
A socket type device that fits over the cap with a short handle
A socket type device that fits over the cap with a thick handle
A socket type device that fits over the cap with a handle that bends 90 towards the table
To decrease pressure, you can either increase decrease( increase, decrease ) surface area, decrease increase( decrease, increase ) force or both.
You are at an increased risk of falling when you shift your center of gravity outside your base of support.
Which of the following is the most stable base of support?
One foot
Two feet
C cane
Quad cane
What biomechanical changes occur during pregnancy?
The added weight on the abdomen shifts the center of gravity
Counterbalancing the added weight puts more force on the low back
Feet swell in an effort to increase the base of support
Gait stance widens to increase the base of support
