Torque and Rotational Motion¶
This chapter explores rotational analogs to linear motion.
Key Concepts:¶
Torque
Rotational kinematics and dynamics
Moment of inertia
Angular momentum
Sample Question:¶
A force of 8 N is applied perpendicular to a wrench 0.3 m long. What is the torque?
\[\tau = rF = 0.3 \times 8 = 2.4\ \text{N m}\]
