Forces, Rotation & Equilibrium — Chapter overview · Physics & Environmental Science, Grade 12
Use force diagrams, friction, circular motion, springs, and torque to explain motion and balance.
Chapter question
Which interactions explain acceleration or equilibrium?
Units in this chapter
- Unit 3.1 · Newton's Three Laws of Motion
I can state Newton's three laws of motion and explain inertia as an object's resistance to changes in motion.
- Unit 3.2 · Free-Body Diagrams & Net Force
I can draw a free-body diagram that shows every force acting on a single object as a labeled vector.
- Unit 3.3 · Friction & Common Forces
I can distinguish static from kinetic friction and calculate a friction force using f = μN.
- Unit 3.4 · Circular Motion & Gravitation
I can calculate centripetal acceleration (a = v²/r) and centripetal force (F = mv²/r) for uniform circular motion.
- Unit 3.5 · Springs, Torque & Static Equilibrium
I can calculate spring force and energy within an elastic model.
