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**

**right-hand rule**

**Convention 1**

**special case of the right-hand rule in two dimensions**

**Convention 2**

*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**
