• Energy and Work (chapter 6)– Kinetic, Potential Energies– Spring energy– Work done by external force = Fxd

• Circular Motion (ch 5)– Centripetal acceleration = v²/r– Circular motion problems are newton’s 2nd law

problems with a = F/m– Always draw force diagrams, right?

• Universal Gravitation (ch 5)– Newton’s universal gravitation force

connected the laws on earth to those in the sky.

– There will be a couple of questions on the test regarding this.

• Torque and Rotational Equilibrium (ch 9)– Torque problems are static problems with no

acceleration, so all the forces are balanced and all the torques must be balanced about any point you choose.

• Simple Harmonic Motion of Spring and Pendulum (ch 11)– Simple Pendulum period depends only on

length of the string– Period of oscillating spring depends only on

the mass and spring constant k
