Sagittal Plane
Divides the body into left and right parts.
Frontal Plane
Divides the body into anterior and posterior parts (front and back).
Transverse Plane
Divides the body into superior (top) and inferior (bottom) parts.
Medial/Lateral Axis
Axis associated with movements in the frontal plane.
Anterior/Posterior Axis
Axis associated with movements in the sagittal plane.
Polar/Longitudinal Axis
Axis associated with movements in the transverse plane.
Flexion
Decreases the angle between two segments.
Extension
Increases the angle between two segments.
Abduction
Movement away from the midline in the frontal plane.
Adduction
Movement towards the midline in the frontal plane.
Internal Rotation
Anterior surface rotates towards the midline.
External Rotation
Posterior surface rotates away from the midline.
Torque
The rotational force around an axis.
Work
The energy transferred when a force is applied over a distance.
Kinetic Energy
Energy possessed by an object due to its motion.
Potential Energy
Energy stored in an object due to its position or configuration.
Momentum
The quantity of motion of a moving body, measured as a product of its mass and velocity.
Moment of Inertia
A measure of an object's resistance to changes in its rotation.
Ground Reaction Forces
The forces exerted by the ground on a body in contact with it.
Newton’s 3 Laws of Motion
Fundamental principles that describe the relationship between a body and the forces acting on it.
Velocity
The speed of an object in a given direction.
Acceleration
The rate of change of velocity of an object.
Displacement
The change in position of an object.
Energy Conservation
The principle that energy cannot be created or destroyed, only transformed.
Joint Classification
Categories of joints based on their structure and function, such as diarthrodial.
Angular Kinematics
The study of the rotation of bodies and the relationships among angular displacement, velocity, and acceleration.
