Published	10/26/2023	What happens when your line of gravity leaves your base of support?
Published	10/26/2023	Name 3 ways to ensure you are stable
Published	10/26/2023	Define Newton's Laws of Intertia and Accelereation
Published	10/26/2023	Define the Law of Action-Reaction
Published	10/26/2023	Reaction forces are always in the same line and applied to the different but contacting objects.The directions of reaction forces are always {{c1::opp…
Published	10/26/2023	By {{c2::increasing}} the Moment Arm for a muscle force, a force of the same magnitude produces {{c1::greater}} torque.
Published	10/26/2023	Equation for Equillibrium
Published	10/26/2023	Explain how you can get mechanical advantage with a first class lever
Published	10/26/2023	Provide examples of First Class Levers

Published	10/26/2023	Most levers in the body are {{c1::3rd Class Levers}}
Published	10/26/2023	In a third class lever:The {{c2::Effort}} Arm will always be {{c1::smaller}} than {{c2::Resistance}} Arm
Published	10/26/2023	In a second class lever:The {{c2::Effort}} Arm will always be {{c1::Larger}} than {{c2::Resistance}} Arm
Published	10/26/2023	Examples of Third Class Levers
Published	10/26/2023	If the Biceps is eccentrically contracting, what is the effort force and resistance force? How does this affect the lever?
Published	10/26/2023	When a lever is in rotational equilibrium, the muscle acting on the lever is contracting {{c1::isometrically}}. In such a case, labeling the muscle as…
Published	10/26/2023	When a muscle is contracting eccentrically (actively lengthening), the muscle must be acting in a direction opposite to the motion of the segment; tha…
Published	10/26/2023	Mechanical Advantage Equation
Published	10/26/2023	The {{c1::second}} class lever is always efficient, M Adv greater than one, although the magnitude of the ratio of EA to RA will vary.   In …
Published	10/26/2023	Third Class Levers, {{c1::EA}} is always smaller than {{c1::RA}} since the effort force lies closer to the axis than the resistance.M Ad of the third …
Published	10/26/2023	What is the benefit of 3rd class levers?
Published	10/26/2023	Work formula
Published	10/26/2023	Like all other forces, the Moment Arm of the force of gravity is always greatest when the force is applied at {{c1::90}}° to the lever.
