End Of Year

Tension- The force on a string/rope. Our swing had tension in the ropes holding it up

Angular Momentum- The angular equivalent to momentum and is always conserved. L=Iω 

Torque- The angular equivalent to linear force. T=2π/ω

Gravitational potential energy- Energy an object has due to its height Ug=mgh

Translation kinetic energy- The energy an object has due to its linear velocity. Kt=1/2mv^2

Rotational kinetic energy- The energy an abject has due to rotational velocity. Kr=1/2Iω^2.

The goal of this project was to design and create a functional tree swing. Using our knowledge of forces, torques, and harmonic motion, we analyzed our swing and the components related to its function. 

Our design was a wooden board held up on a tree with ropes. We set up our swing and used videos to analyze the speed and height that it could reach. We also added a component of rotation by spinning the rider as they moved on the swing. We used our data and related to the content we learned in class to create and present out our funnest swing design.

Velocity- The speed of an object in a given direction

Acceleration- the change in velocity over time

Fgravity- The force exerted on an object due to gravity

Fpush- The force exerted on an object due to an outside force of push

Potential energy- The energy an object has due to its position in a gravitational field

Kinetic energy- The energy an object has due to its velocity. 

For our final project, we decided to rebuild our fast car forces project from the beginning of the year. We redesigned and rebuilt our original design to be big enough to support a person. We included changes like a car seat and a steering system.

We incorporated concepts from throughout the year like forces, kinematics, and energies when analyzing our final design. We plan to incorporate these findings into a presentation while making further improvements.
