... I needed to chime in on the current discussion of which force/property terms tend to cause confusion, and might therefore be avoided. I find that my students tend to confuse the terms normal force (Fn) and net force. Unless I'm very careful (and sometimes even then) some will start thinking off bot ...

Centripetal means “toward the center.” The force directed toward a fixed center that causes an object to follow a circular path is called centripetal force. Centrip ...

... The rigid body shown rotates about an axis through its center of mass and perpendicular to the paper. If M = 2.0 kg and L = 80 cm, what is the kinetic energy of this object when its angular speed about this axis is equal to 5.0 rad/s? Neglect the mass of the connecting rod and treat the masses as pa ...
