When two forces act at different points on an object in opposite directions, what type of motion is produced? * Rotation / torque Equilibrium — the object remains stationary Linear translation in the direction of the greater force Acceleration in the direction of the smaller force This field is required. Two equal forces act on the same point of an object but in exactly opposite directions. What is the result? * The object rotates around a central axis The object reaches a state of equilibrium and does not move The resultant force equals the sum of both forces The object accelerates in the direction of the larger force This field is required. The frontal (coronal) plane divides the body into which two portions? * Medial and lateral portions Front (anterior) and back (posterior) portions Right and left halves Upper and lower halves This field is required. In biomechanics, what does the of a force refer to? How much force is applied, represented by the length of an arrow The direction in which the force is applied The type of muscle contraction producing the force The number of joints involved in the movement Which of the following best describes an in human body movement? An imaginary flat surface on which movement occurs The midline dividing the body into equal halves An imaginary line about which movement occurs The base of support for the body during standing Where does the sagittal axis (transverse axis) run in relation to the body? * Horizontally from front to back, perpendicular to the frontal plane Horizontally from side to side Vertically from head to toe Diagonally from shoulder to hip This field is required. Shoulder abduction and adduction are examples of movements that occur in which plane? * Transverse plane Sagittal plane Frontal plane Horizontal plane This field is required. Which of the following is an example where muscular force equals the force of gravity, resulting in a stable, stationary position? * Holding a dumbbell still during isometric contraction Bending the spine laterally to one side Rising up onto the toes using calf muscles A ball sinking to the bottom of a pool This field is required. Where is the center of gravity (CoG) located in the human body? * At the level of the second sacral vertebra (S2) At the level of the fifth lumbar vertebra (L5) At the level of the first sacral vertebra (S1) At the level of the navel (umbilicus) This field is required. Elbow flexion and extension (e.g., a bicep curl) occur in which plane and around which axis? * Sagittal plane / Frontal axis Transverse plane / Vertical axis Frontal plane / Vertical axis Frontal plane / Sagittal axis This field is required.
