Simple Harmonic Motion

Question 1

Conditions for Simple Harmonic Motion

Answer 1

• Acceleration is proportional to Displacement
• Acceleration acts in the opposite direction to the
  displacement

Question 2

Mechanical Energy

Answer 2

Sum of the Kinetic Enerdy and the Potential Energy

Question 3

Free Virbations

Answer 3

No Energy transfer to or from the surroundings

Question 4

Forced Vibrations

Answer 4

Occurs when an external driving force is applied

Question 5

Resonance

Answer 5

When the driving frequency equals the resonant frequency/natural frequency, the system gains more and more energy. amplitude rapidly increases until the system destroys itself

Question 6

Light Dampening

Answer 6

Amplitude decreases, decreasing by the same amount each time, T is independent of A

Question 7

Heavy Dampening

Answer 7

A system returns back to equillibrium slowly without oscillating

Question 8

Critical Dampening

Answer 8

System returns to equillibrium in the shortest possible time without overshooting

Question 9

General Dampening Definition

Answer 9

Energy is lost from a system due to frictional forces
