Examples of rigid body in the following topics:



 We can describe the translational motion of a rigid body as if it is a point particle with the total mass located at the COMâ€”center of mass.
 We can describe the translational motion of a rigid body as if it is a point particle with the total mass located at the center of mass (COM).
 Derive the center of mass for the translational motion of a rigid body

 Free body diagrams use geometry and vectors to visually represent the problem.
 In physics, most problems are solved much more easily when a free body diagram is used.
 First you want to model the body, in one of three ways:
 What to include: Since a free body diagram represents the body itself and the external forces on it.
 Explain the significance of building a free body diagram in physics




 Those two conditions hold regardless of whether the object we are talking about is a single point particle, a rigid body, or a collection of discrete particles.

 If two objects are connected by a perfectly rigid connector then they may be thought of as the same object.
 Perfectly rigid connectors cannot stretch nor deform, and transfer forces instantaneously from one side of the connection to the other.
 Thus it can be said that a perfectly rigid connection makes two objects into one large object.
 However, many materials are sufficiently rigid, so that using the perfectly rigid approximation is useful for simplicity's sake.
 Analyze the affect a rigid connection has on the movement of objects
