Oscillations

1. What Are Oscillations?

• oscillation
• cycle
• period
• equilibrium point
• restoring force
• displacement
• alternating current
• amplitude

2. Period and Frequency

• period
• frequency
• hertz
• $f=\frac{1}{T}$

3. Block on a Spring

• relaxation length
• $T=2\pi \sqrt{\frac{m}{k}}f=\frac{1}{2\pi }\sqrt{\frac{k}{m}}$

4. Pendulum

• pendulum

5. Simple Harmonic Motion

• simple harmonic motion
• initial phase
• $y(t)=A\cos (2\pi \frac{t}{T}+{\varphi }_0)$
• $y(t)=A\cos (2\pi ft+{\varphi }_0)$

6. History Graphs

• history graph

7. Velocity and Acceleration

• $v_{max}=2\pi fA{a}_{max}=4{\pi }^2{f}^{2}A$

8. Energy

• $E_{tot}=\frac{1}{2}k{A}^2$

9. Damped Oscillation

• damped oscillation
• underdamped
• overdamped
• critical damping

10. Forced Oscillation
