Chap. 2 Force Vectors
... When a rigid body undergoes only translation, all the particles of the body have the same acceleration so aG = a and α = 0. The equations of motion become: Σ Fx = m(aG)x Σ Fy = m(aG)y Σ MG = 0 Note that, if it makes the problem easier, the moment equation can be applied about other points instead of ...

... centre of mass of a system of particles, then only the external forces count. If you throw a wriggling, squealing cat then its internal forces Fij can change its orientation, but they can do nothing to change the path of its centre of mass. That is dictated by gravity alone.

... d) The center of gravity of an object may be thought of as the "balance point." Solution: Depending on the shape of the object, the center of mass of the object could be outside of the object’s body. Thus C) above is a false statement. 21. A plane, flying horizontally, releases a bomb, which explode ...

Rotational Motion Objectives: After reviewing this section you should
... You will recall that circular motion is the motion of an object in a curved path about an external axis. This week we will explore a similar situation. Rotational motion is motion of an object in a curved path about an internal axis. The word 'angular' is used to describe motion in a circular path. ...
