The four particles in Figure P10.45 are connected by rigid rods of negligible mass. The origin is at the center of the rectangle. The system rotates in the xy plane about the z axis with an angular speed of 6.00 rad/s. Calculate (a) the moment of inertia of the system about the z axis and (b) the rotational kinetic energy of the system.
Chapter 2 PHYS 1220 Kinematics-The careful description of motion that is independent of its cause Dynamics- Involves the cause of motion One-Dimensional Kinematics- motion can be rotational, vibrational, or translation Rotational motion- A spinning motion Vibrational Energy- Back and forth motion Translation Energy- Moving from point a to point b o A translating object can be shown as a particle Most kinematics are shown with vectors o A vector has a magnitude and a direction o A scalar is a quantity that has no direction and is only magnitude Kinematics can be expressed by using a motion diagram o A motion diagram is an illustration that will depict an object at dif
