Oscillations

Question 1

What is the lowesty point called on an oscillating object

Answer 1

• equilibrium
• where the object will eventually come to a stand still
• objects are oscillating about the equilibrium

Question 2

What is the displace of an oscillating object?

Answer 2

• change in distance or direction from equilibrium position

Question 3

Describe the displacement of the object oscillating

Answer 3

• displacement decreases as it returns to equilibrium
• then reverses and increases as it moves away from equilibrium in the opposite direction
• decreases as ut returns to equilibrium
  
  • increases as it moves away from equilibrium towards its starting position

Question 4

What is the amplitude of the oscillations

Answer 4

• the maximum displacement of the oscillating object from equilibrium

Question 5

What is the time period of the oscillating motion

Answer 5

• the time for one complete cycle of oscillation
• one full cycle after passing through any position, the object passes through that same position in the same direction

Question 6

What is the frequency of oscillations?

Answer 6

• number of cycloes per second made by the oscillating object
• f = 1 / T

Question 7

What is the angular frequency?

Answer 7

ω = 2π / T = 2πf

rads per second = rad s^-1

Question 8

What is the equation for the phase difference for two objects oscillating at the same freuqncy in radians?

Answer 8

2πΔt / T

where Δt is the time between successive instants when the two object are at maxiumum displace in the same direction
