AP Physics B Topics for Test 3

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

AP Physics B Circular Motion (ch 5) –Centripetal acceleration = v²/r –Circular motion problems are newton’s 2 nd law problems with a = F/m –Always draw force diagrams, right?

AP Physics B 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.

AP Physics B 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.

AP Physics B 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
