Boat Racing

We decided to do something different rather than working through our scipads, for the past weeks we have been working on designing and creating our own wind yachts so that we can race them, calculate the speed and see how forces work when we use a wind blower, we also went over aerodynamics and how we can improve the speed. 

AIM - Our goal was to create a yacht that would be pushed a reasonable distance when pushed using a leaf blower. 

METHOD - 

1 - Design on paper the base and the sails of the yacht and keeping in mind aerodynamics and how we can make the yacht as fast as possible. 

2 - Gather the materials that you need to create the yacht - 
Plastic bag 
Cart/with wheels
Bamboo stick 
Tape 
Scissors 
Popsicle sticks 
Skewers 
Leaf Blower (Wind source) 

3 - Put together your yacht using the materials that you have available (We used the plastic bag for the sails and the skewers and bamboo stick for the framework, The popsicle sticks to make a sloped surface so that the air could fly past easier) 

4 - Using a measuring tape and a stopwatch, line up your yacht and turn on the leaf blower aiming it at the sails and measure the speed and the distance it traveled. 

5 - Using the results from the race, calculate the speed. 

RESULTS - 

Miah = 2.6m(Distance) 13.6s(Time) 0.191m/s(Speed) 
Kade = 4.2m(distance) 6.4s(Time) 0.656m/s(Speed)
Jayden = 1.7m(Distance) 7.3s(Time) 0.233m/s(Speed)
Ranit = 1m(Distance) 4s(Time) 0.25m/s(Speed)
Aili = 4.5m(Distance)7.3s(Time) 0.616m/s(Speed) 

CONCLUSION - 

The fastest yacht that we raced was Kade's yacht which raced at a speed of 0.656m/s closely followed up by Aili's team with a speed of 0.616m/s. This was due to the size of their sails being less aerodynamic, with bigger sails more of the wind tat was produced by the leaf blower got caught in the sail, accelerating the yacht forward at a higher speed. Opposed to tat mias yact travelled at te lowes speed because te sail was smaller meaning it caught less of te wind to accelerate it forward and oppose te oter forces at play, wic was te weight force, support force and te friction force.
