Chapter 7: Rotation I: Kinematics, Force, Work, and Energy

Angle

Defined to be the ratio of a circular arc to its radius according to the equation θ \= arc length/radius

Conversion between units for θ

Angular displacement , given by the equation is analogous to linear displacement

Definition of angular velocity

Definition of angular acceleration

v \= rω

Relationship between speed and angular velocity

Definition of Rotational Inertia

rotational kinetic energy

Torque

The ability of a force to cause an object to accelerate angularly

Definition of Torque

Newton-meter

The unit of Torque

Work done by a constant torque
