For the previous lessons we have been looking over what we are going to be doing in our upcoming unit in which we are designing a kart that will race along a track. In order to complete this assessment I will need to find out (through trial and error as well as mathematical equations) which design will help the kart be propelled faster down the track.
Variables that will effect the speed will include
- weight (KE = 1/2 mv)
- how close the battery is to the gear box (how much energy is wasted in traveling through the wires)
- the shape of the kart (how streamlined it is will effect the air resistance)
- what gears to use (fast acceleration but slow overall speed or slow start but higher full speed)
- the friction in the wheels to the ground, the gear wheels, (what lubricants to use)
We will also have some theory work to do after the assessment which will include finding the velocity, acceleration, and KE.
