As you increase the length of a ramp, you decrease the angle that the ramp has to make with the ground.
A greater angle will result in greater acceleration. Thus, a shorter ramp/shorter displacement will result in increased acceleration. Whereas, a longer ramp will result in decreased acceleration.
I have drawn a little picture to help us think about this (prepare yourself for what is sure to be the best drawing you've ever seen in your entire life - no cap):
As you can see on the image above, we have two people who are about to roll down a hill. In condition 1, the ramp is longer - meaning the angle is smaller. In condition 2, the ramp is shorter - meaning the angle is larger.
Who do you think will roll down the hill faster? The person in condition two, right? Yes. Honestly, that hill looks like it would hurt to roll down lol.
Hope this makes sense :)

Hi does anyone recommend memorising all the notes we're given in class by our teachers or just the syllabus dot points?

I had my fair share of teachers who covered content that wasn't super important. I would recommend putting all of the syllabus dot points onto a word document and filling your notes underneath each dot point so that you know you've covered it all. At least for the theory-based dot points. For the practical-based calculation type dot points, just do practice questions. I noticed you asked the same question for biology, I recommend this method for that as well. It ensures that you have everything you need.

Thanks so much for the advice!! I've had a bit of a hectic year with so many of my teachers leaving my school and me just trying to survive the school year...I really appreciate this!

just a quick question, if a study I'm using may be slightly outdated, does it affect its reliability or validity?
thanks!
