Newton's First Law

Law of Inertia- An object at rest stays at rest, an object in motion stays in motion.(Unless acted on from an external force)

Newton's Second Law

Law of Acceleration- Acceleration is directly proportional to the force causing it. Force=Mass x Acceleration.

Newton's Third Law

Action, Reaction- every action has an equal opposite and concurrent reaction

4 Laws of motion

No Displacement (stationary)- Center of mass must be over base.




Linear Displacement- If forces pass through center of mass, they cause linear motion.




Angular motion- if off center they produce rotational(angular) motion.




Motion to stationary- Attenuate energy (ex) running into a wall.





The "levers" of the body.

Skeletal Segments (ex) leg while walking

The "Axis" of the body

Joints

Define Acceleration

A change in velocity

Standing with Palms Forward, Thumbs outwards

Define frontal plane and give an example of its version of adduction and abduction.

Divides the front and back, abduction:arm out and up, adduction: resting position

Define saggital plane and give an example of its linear movement, flexion and extension.

Divides body into right and left sides. Linear movement: walking, Flexion: Bicep curl, Extension: Bicep resting position

Define Transverse plane, define Supination and Pronation

Define Lateral

Farther from midline (ex) thumb is distal to index finger

Define Deep

Away from the surface (ex) bone is superficial to muscle

Define Superficial

Near the surface (ex) muscle is superficial to bone

Define Proximal

Closer to your body (ex) knee is distal to foot

Define Distal

Farther from your body (ex) Foot is distal to knee
