Questions and Answers

What is the difference between kinematics and kinetics?

  • Kinematics studies motion without considering the forces involved, while kinetics studies the forces causing motion. (correct)
  • Kinematics deals with forces while kinetics deals with motion.
  • Kinematics focuses on energy transfer, while kinetics focuses on speed and velocity.
  • Kinematics focuses on the surface area of objects, while kinetics focuses on their volume.

    • What are the cardinal planes in human motion?

  • Horizontal, longitudinal, and oblique planes
  • Frontal, sagittal, and transverse planes (correct)
  • Frontal, sagittal, and oblique planes
  • Transverse, longitudinal, and horizontal planes

    • What do medial and lateral refer to in anatomy?

  • Medial refers to movement above the head, while lateral refers to movement below the waist.
  • Medial refers to movement towards the head, while lateral refers to movement towards the feet.
  • Medial refers to movement away from the midline, while lateral refers to movement towards the midline.
  • Medial refers to movement towards the midline, while lateral refers to movement away from the midline. (correct)
