This is one of the twelve images that make up "The Horse in Motion", copyright 1878 by Eadweard Muybridge and now available via Creative Commons license. In this image, the two front legs are rotating in opposite directions from our point of view one clockwise and one counter-clockwise around their respective shoulder joints. These images and those like them helped scientists understand the physics of gross-motor-motion for living things. In your first post, discuss the functional morphology or gait of a person or animal species as it relates to your data and observations. For example: How does a person change the moment of inertia of their arm when beginning to run as compared when they are walking? If you look at a picture of a running horse like the one shown below, can you tell which legs are rotating so that the foot moves toward the front of the horse and which are rotating in the opposite direction? If you watch the movement of a gymnast or diver, find/create a video clip that shows how their motion changes when they change their moment of inertia.
Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.
