hi everyone I'm in my first year of electronic engineering and i have some questions which the professor of physics gave us but more as research than homeworks and to be honest i really tried but i didn't found anythings so I'm here to asking for your help
1- what is the difference between: (A and B are vectors)
A+B
the addition of A and B
the sum of A and B
2-is it true that in physics we have only scalars and vectors as quantities ?
3-is it true that all quantities which have direction and magnitude are vectors ?
4-what is the difference between the displacement and the path ?
5-how using the significants figures contributed in the scientific development ?
6- if you have the time and space can you find all other variables in physics ?
7-acceleration has no scientific meaning , why ?
8-the body of human is an accelerometer ,why ?
9-the body of human is not a speedometer ,why ?
if you can give me the answers or just tell me where i can found them it will really help me
