Transcript

  • 1. PhysicsA natural occurrence
  • 2. Objectives• Examine gravity and see its effects on the ocean’s tides• Examine the concept of resonant frequency• Use the above physical properties to explain why the Bay of Fundy has the highest tides in the world
  • 3. Gravity F = Gm1m2/r2F is the force due to gravity, between twomasses (m1 and m2), which are a distance rapart; G is theThe force of attraction that moves ortends to move bodies towards thecentre of a celestial body, such as theearth or moon
  • 4. Gravity and the Ocean’s Tides• Moon’ gravity pulls on the Earth causing the earth to distort in shape.• Tidal Simulation
  • 5. Resonant Frequency• the state of a system in which an abnormally large vibration is produced in response to an external stimulus, occurring when the frequency of the stimulus is the same, or nearly the same, as the natural vibration frequency of the system.• Bridge at resonance
  • 6. The Bay of Fundy• Found between western Nova Scotia and eastern New Brunswick• Highest Tidal levels in the world Maximum tides of 16 meters (53 feet) seen in the Minas Basin in Nova Scotia
  • 7. Putting it All Together• The moon’s gravity causes tidal swings at a of period of just over 12 hours• The Bay of Fundy has a resonant period of just over 12 hours.• Because the bay’s resonant frequency happens to equal the frequency of the ocean’s tidal swings, The Bay of Fundy’s tide are much larger then any other tides in the world.
