AP Physics B

1
AP Physics B

• Topics for Test 3

2
AP Physics B

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

3
AP Physics B

• Circular Motion (ch 5)
• Centripetal acceleration v²/r
• Circular motion problems are newtons 2nd law
  problems with a F/m
• Always draw force diagrams, right?

4
AP Physics B

• Universal Gravitation (ch 5)
• Newtons 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.

5
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.

6
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
