100
the force in parallel between two surfaces that resists sliding of surfaces past each other
What is Friction
200
the addition of vectors to obtain their net effect (see "net force")
What is Resultant
200
the contextual, theory-based and data-supported ideas that make the best current explanation for reality
What is Knowledge
200
the functional unit of a myofibril; a sarcomere is the region between two Z disks

the downward (vertical) force action on an object due to gravity
What is Weight
300
simple quantity completely defined by a single number (magnitude)
What is scalar
300
Artificial Limbs
What is Prosthetics
300
the large filaments in a myofibril that interact with actin to create muscle tension
What is myosin
300
the capacity to do work of an object due to its vertical position in a gravitational field (gravitational potential energy) or its deformation (strain energy)
What is Potential energy
300
The branch of mechanics that describes the motion of objects relative to some frame of reference
What is Kinematics
400
A technique for study- ing mechanics by creating a diagram that isolates the forces acting on a body
What is Free-body Diagram
400
the increase in size of muscle fibers
What is Hypertrophy
400
a component of muscle tension from passive stretching of mus- cle, especially the connective tissue components
What is passive tension
400
the capacity to do work of an object due to its deformation by an external force
What is Strain energy
400
The resistance of an object to linear acceleration
What is mass
500
the maximum force or torque produced by a muscle group in an isometric action at a specific joint angle; research has found several domains of strength expression depending on the time, velocity, and resistance involved
What is Strength (Muscular)
500
the small cylindrical filamentsthat make up a muscle fiber/cell
What is Myofibril
500
a part of the Hill muscle model that represents the passive tension from connective tissue throughout the muscletendon unit
What is parallel elastic component
500
work is done when a force moves an object in the direction of the force and is calculated as the product of force and displacement
What is Work (mechanical)
500
The branch of mechanics studying the motion of bodies under acceleration
