![]() ![]() ![]() To locate a point mass in three-dimensional space requires only three coordinates: X, Y, and Z. These three translational and three rotational movements define the six degrees of freedom (DoF) of a rigid body in 3D space. But it can also rotate around the X, Y, and Z axes, creating rotational motions referred to as roll, pitch, and yaw, respectively. It can make translational movements forward and back, left and right, and up and down in the X, Y, and Z axes. The classic example of a rigid body in three-dimensional space is an aircraft in flight. ![]() The six degrees of freedom (DOF) include three translational motions and three rotational motions. But a rigid body can both move, or translate, along these three axes and rotate about them, so we need three translational (X, Y, and Z) and three rotational coordinates (rotation about X, Y, and Z) to locate its position. If the object is a point mass, we only need three coordinates (X, Y, and Z) to locate its position. To identify the position of an object in three-dimensional space, we use a coordinate system that defines three axes: X, Y, and Z.
