Hello All,
A lot of you are probably physics majors so this question will sound dumb to you, but I am just in A.P. Physics 1 in high school... we are learning projectile motion and the teacher is not the best at explaining it. We had our first test a few days ago, everyone bombed it, and he didn't care...:L... anyway, the reason we all tripped up is because we had a lot of conceptual questions instead of plugging in numbers into formulas like we practiced. I know it's really crucial to know these things so here's my question: what are the relationships among initial velocity, acceleration, displacement, and time in 1-D problems? The same goes for 2-D problems (except that there are two numbers for each value in x and y). "Two cars are traveling with the same velocity, they step on the brake at the same time, except one twice as much (with a 2x acceleration). What is the relationship in the time that it takes the two cars to stop?" I guess what I'm going at is what are the correlations between all of these factors, I think it will help me for my tests, and for my understanding of conceptual physics.
Thank you all so much for your help. :)
