For example, a force acting along the Z-axis is resolved into its components along the xyz axes in the above three equations. Note that the subscripts x,y,z indicate that the quantities are resolved along the xyz axes. They are:Р”Р„ Gx is the acceleration of the center of mass G in the x-direction, with respect to ground (an inertial reference frame)Р”Р„ Gz is the acceleration of the center of mass G in the z-direction, with respect to ground The first three of the six scalar equations describing the motion of the body are force equations. This is the most general case for a rigid body.Р”Р„ general rigid body subjected to arbitrary forces in three dimensions is shown below. The Physics Of A Golf Swing Trebuchet Physics Three-Dimensional Rigid Body DynamicsР”Р‡or three-dimensional rigid body dynamics problems, the body experiences motion in all three dimensions, due to forces acting in all three dimensions.

Here are some examples of problems solved using two-dimensional rigid body dynamics equations:

A specific example of this would be a pendulum swinging about a fixed point. Where the point O is a fixed point, attached to ground. The figure below illustrates this situation. Note that, if the rigid body were rotating about a fixed point O, the final moment equation would retain the same form if we were to choose point O instead of point G. I G is the rotational inertia of the rigid body about an axis passing through the center of mass G, and pointing in the z-direction (out of the page) Using РћР€M G is simply a different naming convention. This is defined as the sum of the torque РћР€ РџвЂћ due to the forces acting on the body (about an axis passing through the center of mass G, and pointing in the z-direction). РћР€M G is the sum of the moments about an axis passing through the center of mass G (in the z-direction, pointing out of the page). РћвЂ is the angular acceleration of the rigid body with respect to ground РћР€F y is the sum of the forces in the y-directionР”Р„ Gx is the acceleration of the center of mass G in the x-direction, with respect to an inertial reference frame xyz, which is the ground in this caseР”Р„ Gy is the acceleration of the center of mass G in the y-direction, with respect to ground РћР€F x is the sum of the forces in the x-direction
