Playland Pirate Ship Physics

The

Pirate Ship

The Pirate Ship is an amusement park ride that uses a combination of mechanics and gravity in order to swing its riders in a pendulum motion. It has been a popular attraction at Playland since its opening in 1984.

Data

Vertical Height of Ride: 20 m

Height at Highest Peak: 12.33 m

Number of Complete Swings: 11

Duration of One Swing: 7 s

Total Ride Duration: 136 s

Mass: 2000 kg

What causes gravity?

Gravity is the downward magnetic force that pulls all objects with mass towards the center of the Earth.

What is friction?

Friction is the force that resists motion in an object. Static friction keeps an immobile object at rest, while kinetic friction slows down a moving object.

The Physics

of the Ride

A large wheel underneath the Pirate Ship's body initiates the

movement of the ride. The wheel pushes the ship from side to

side, gradually accelerating and rising higher into the air. As the ship reaches its highest point with its given velocity, gravity pulls it back down towards the Earth, and the arms suspend it in a pendulum motion. If this were a freestanding ride, it would eventually slow down after reaching its apex due to external

factors such as kinetic friction on the wheel, wind resistance, and

mechanical friction in the rides joints and arms. These external

forces would cause the system to lose energy in the form of

heat, sound, and other forms of resistance. However, in

reality the wheel acts as a brake, slowing the

swinging motion down to a stop.
