Basic Principles

Question 1

8 Figure

Answer 1

Particular type of arc with the shape of an 8.

Question 2

Arcs

Answer 2

Usual path of a structure with joints.

Question 3

Balance

Answer 3

Balance is when the sum of forces and momentums of all the parts of the body are canceled.

Question 4

Biomecanics

Answer 4

Interdisciplinary area of ​​knowledge that studies the kinematic and mechanical phenomena of the living beings as a complex systems composed by tissues, solids and mechanical bodies. That’s why biomechanics is interested in movement, balance, physics, the resistance, injury mechanisms that may occur in the human body as a result of various physical actions.

Question 5

Body Angles

Answer 5

Angles formed by the line of the pelvis with shoulders.

Question 6

Body Dynamics

Answer 6

Part of physiology that studies the activity of biological phenomena.

Question 7

Breaking joints

Answer 7

Bending a joint in the opposite direction to its normal rotation, which create the illusion that this position looks broken. It is used to create the illusion of flexibility and make it look like a piece of flexible rubber.

Question 8

Cycle

Answer 8

Repetition of any periodic phenomenon, in which, after a certain time, the state of the system or any of their magnitudes return to a previous configuration. In animation, generally, that term refers to walking or running cycles.

Question 9

Drag

Answer 9

Or Wave Principle, occurs as a result of friction or resistance, such as air or water, or because different parts of a character are receiving different amounts of inertia.

Question 10

Follow through

Answer 10

When a character changes direction and parts of his body continue in the direction it was previously.

Question 11

Force

Answer 11

Any agent able of modifying the amount of movement or shape of the materials.

Question 12

Fulcrum

Answer 12

Supporting point.

Question 13

Mass

Answer 13

Measurement of the amount of matter that a body have.

Question 14

Overlap

Answer 14

When the different parts of a body continue the movement once the character stopped.

Question 15

Overlapping action

Answer 15

The action of offsetting a mouvement to avoid that everything arrives at the same time. This allows us to simulate flexibility and avoid that the movement seems rigid.

Question 16

Path of action

Answer 16

Path through which passes the center of a moving object.

Question 17

Physic Laws

Answer 17

Theoretical principle deducted from facts, applicable to a set of phenomena and can be stated as a particular phenomenon that always occurs if certain conditions occur.

Question 18

Power center

Answer 18

Imaginary point that seems to be the energy source of a character that influences his posture, gestures and actions.

Question 19

Slow in

Answer 19

Deceleration. Slowing in to the pose.

Question 20

Slow out

Answer 20

Acceleration. Slowing out of the pose.

Question 21

Squash and stretch

Answer 21

That means compression (Squash) and stretching (Strech) of an animated object without changing its apparent volume.

Question 22

Successive Breaking Joints

Answer 22

Overlap principle applied to a chain of bones (for example, as the arm) to give flexibility to a movement.

Question 23

Weight

Answer 23

A measure of the gravitational force acting on an object. The weight equals the force exerted by a body on a support, caused by the action of the local gravitational field on the body mass.

Question 24

Weight shift

Answer 24

Weight change from a fulcrum to another.
