F = ma
This adventure is a look at Newtons second law in equation form, "the resultant force of an object is equal to the objects mass x acceleration". This sounds easy until you apply it to real world problems. Many of my experiences with F=ma are to do with Vectors and pulleys in A level mechanics and I really enjoy it. I haven't really encountered any questions in physics to use F = ma. However many of the physics problems I do can be done in so many different methods - all with the same thinking - to achieve the same answer like SUVAT questions or electricity.
The most common use of F=ma in my mechanics A-level is friction on slopes or just friction on a rough surface, but sometimes it is smooth. Due to the absurd amount of questions that you can get for this topic I will not be doing any example questions, instead a series of posts would be better. Nonetheless I will go through the types and over time I will update this post with the designated posts for each type.
The first type is the Suva type, usually you are given the mass and a force on a block and need to find the acceleration. In general the questions demand you to find the acceleration.
You then have the inclined slope questions, where you have friction included almost every question. These questions are really hard for me, whether it is because it is foreign to me as I need to more time for it to marinate in my head.
You then have pulleys and now inclined pulleys. The questions are essentially simultaneous equations where the resultant forces are equivalent to the mass x acceleration.
Finally you have ladders. I have done 2 questions and I hate them. Again this is foreign to me so hopefully in die time it will make sense to me.
To conclude this adventure has been fun for me to write as it is sort of a progress tracker for me on how confident I feel about mechanics. I can't wait for the day that this was easy for me.
