A force must act on a body which, as a result undergoes motion in the direction of the force.
because its motion is done repeatedly
"Work is done on an object if two things happen: (1) the object moves as a force is applied and (2) the direction of the object's motion is the same as the direction of the force.".SOURCES:Dumas, Leila, and William G. Lamb, Ph.D. "Chapter 1, Section 1: Work and Power." Holt Science & Technology: Forces, Motion, and Energy. Austin: Holt, Rinehart and Winston, 2005. 95. Print.
Our jumping is a vertical motion, while walking is a horizontal motion. Exercises are done by both horizontal and vertical motion.
When force is opposite to the direction of motion, no work is done. The object to which the force is applied must move in the direction of the force in order for work to be done.
It will depend on the task to be done. Consideration must be given to the type of work to be performed, visibility, whether reading is a factor, reaching distance, and force requirement. Precision work (repacking medications) requires 37-43 in. from floor to elbow height, lighter work (preparing labels) 34-37 in. from floor below elbow height, and heavy work (making blister pack cards) 28-35 in. below elbow height. Elbow height is defined as the distance between the ground and the individual's elbow when the individual stands with his/her arms relaxed at his/her sides.
A force must act on a body which, as a result undergoes motion in the direction of the force.
The type of radiograph that should be performed by only a veternarian is any on done of the spine or an elbow injuries. Also any pelvic inuries that may occur.
If it's on or around the elbow yes. I had mine done not unbearable but you'll feel it. Good luck.
no
because its motion is done repeatedly
No one has yet touched their ear with their own elbow.
a push up (shoulder horizontal abduction/adduction, elbow flexion/extension, and scapular retraction/protraction) is done around a vertical axes, in the transverse plane, while lying pronated. The axes of motion change relative to the body so a vertical axes will not always be perpendicular to the ground but more importantly traverse through the body from head to toe regardless of the body's relative position to earth.
I had this happen in my right elbow elbow. so I had the joint cut out and a new metal one put in to replace it. We cant replace cartilage yet. but they are working on it.

That's done so that all the processes in the hand are immobilized during the time required for healing. Tug on a tendon in your forearm, and I move your hand up and down. Full arm casts help to prevent that accidental motion.
