Explore the Planetary Olympics: An Exhibition on Gravitational Effects and Extraterrestrial Sports

1. Planetary Olympics Exhibition The Collective Universal Gravitation The Planets Extra Features

2. General Workings of the Exhibition • The Gravitational Field • Simulates various gravitational strengths of each planet • The Planets and Respective Sports • Simulate various sports as if they were played under environmental factors found on corresponding planet • Extra Features • Other exhibits demonstrating interesting facts or related activities to supplement exhibition theme

3. The Gravitational Field—Field of Gravitations • Gravitational field strength vary between planets (universal law of gravitation) • Environmental Factor: Gravitational force experienced by objects determine their weights • Effect: (equipment-wise) less weight = less energy expended, modified projectile motion

4. The Gravitational Field– Exhibit Design • Demonstration: • Visitors try lifting sports balls of different masses that represent the same ball subjected to different gravitation • Compare throwing an object with low air resistance with one of high air resistance to simulate varied accelerations • Diagram goes here

5. The Venusbird—Venus • Terrestrial and has similar size and composition as Earth • Notable Environmental Conditions: • Hot surface temperature, i.e. exceeds 400°C • High density atmosphere (due to CO2) • Slightly lower gravitational field intensity (~90% Earth) • Higher air viscosity

6. The Venusbird—Badminton • Racket sport with shuttlecock as projectile • Little wind toleration makes Venus surface ideal • Shaped to produce great drag & skewed parabolic path  Highly influenced by atmospheric conditions • Higher air density  slower shuttlecock (buoyancy and drag) • Higher air viscosity  slower shuttlecock • Lower gravitational pull  slower shuttlecock drop • Overall: Aide players due to less demand on reaction time • Concepts: projectile motion & aerodynamics

7. The Venusbird – Exhibit Design • Display board: • Planetary conditions and effect on shuttlecock (& more) • Demonstration: • Transparent displays in which the visitor launches shuttlecocks and observe trajectory on Earth vs. Venus • Fluids of varied viscosity through which the visitor tries to drag objects to experience shuttlecock drag • Diagram is here

8. Galing Gas Giants • All Gas Giants share characteristic high winds and lack of solid surface, hence designated sports take advantage of these features • Jupiter & Saturn  Windsurfing • Uranus  Hang-Gliding • Neptune  Gliding

9. The Glider of Neptune – Neptune • Gas giant with thick atmosphere, liquid surface, and high winds/storms • Notable Environmental Conditions: • Highest wind speeds in solar system (i.e. Up to 2000 km/h) • Great difference in temperature between core and outer cloud tops generate complex weather

10. The Glider of Neptune -- Gliding • Air sport involving glider (i.e. unpowered aircraft); competes for distance and speed • Higher net air speed  more lift • Greater temperature gradient = more thermals  more lift • Unstable weather  turbulent ride • Overall: greater lift  gains higher altitude, stays longer in air, covers greater distance • Concepts: aerodynamic force – lift

11. The Glider of Neptune – Exhibit Design • Display Board: • Planetary conditions and effect on glider • Demonstration: • Live-sized sailplane model, in which visitors sit, simulate glider movement and Neptune sight on screens • Mini gliders behaviour when subjected to various wind conditions (from fans) manipulated by visitors • Diagram goes here
