12 Questions
Internal forces (Fi) are generated by structures located outside the body.
False
Active forces are generally under voluntary control.
True
Passive forces are typically generated by tension in contracted periarticular connective tissues.
False
External forces are produced by forces acting from outside the body.
True
Sir Isaac Newton observed in the 18th century that forces were related to mass and motion.
False
The laws of motion include the Law of inertia, Law of deceleration, and Law of action - reaction.
False
Inertia is directly proportional to the velocity of a body.
False
The center of mass (CoM) and center of gravity (CoG) are always located at different points in a body.
False
Linear acceleration of a body is inversely proportional to its mass.
True
The angular acceleration of a body is directly proportional to the mass moment of inertia.
True
If the sum of forces acting on a body is zero, the body is in dynamic equilibrium.
False
Newton's first law describes situations where a body is compelled by external forces to change its state.
True
Learn about internal and external forces that act on the musculoskeletal system. Internal forces are generated from structures within the body, while external forces are produced by outside factors. Understand the distinction between active and passive forces.
