1. So I have been trying to get my head around the mess that it is my physics coursework but I am just not understanding it.
For the coursework we had to measure a factor that affected how far a ski jumper travelled.
My group chose height.
Now because I am never in I didn't actually do the experiment, so I have no idea what this whole thing is.
In the preliminary results they measured how far it took the ball to get to the bottom of the ramp, and the results showed that the higher the slope, the faster the ball travels.
But then in the actual results, they worked out the speed the ball travelled at from when it left the ramp and the landed, and as the ramp gets higher the speed gets slower, but the distance travelled is documented as further.
2. ISAs are prohibited in the TSR guidelines
3. Familiarise yourself with Speed = Distance / Time. This means that the distance is greater but the speed is slower because it took more time.. The ball had more time in the air. Use proportionality to answer your question, when you increase distance.. Time needs to increase in order to make speed slower. In this case, the time increases more than the distance.
