General planar motion allows for simultaneous rotational and translational motion in a 2-D plane. The motion of the rigid body may be described as a simple superposition of the body's translation and rotation as illustrated in the following figure.
Accordingly, what is the meaning of planar motion?
Plane Motion. the motion of a rigid body such that all its points move parallel to some fixed plane. Such motion is composed of translational motion together with an arbitrarily selected pole around which rotational motion occurs.
Secondly, what is a planar body?
Here is a collection of notes on the planar dynamics of rigid bodies. When we say planar dynamics, we are referring to the dynamics of bodies that can only rotate about a single axis (perpendicular to the “plane”). Kinetic energy of a rigid body (derivation coming). Angular momentum of a rigid body (derivation coming).
General motion is a combination of linear and rotary motions. General motion is the most common type of motion in sport and physical exercise. In this case the trunk moves in linear motion as a result of rotary motions of individual segments of extremities. Riding a bicycle is another example of general motion.
