can someone tell me what these formulas do?
constant velocity(when velocity is constant, which is 0 right?, you use these formulas)...
1.) a(t) = 0 <== when constant velocity, a(t) = 0 right?
2.) v(t) = Vi(what is v(t)? vi = initial)
3.) x(t) = Xi + ViT (what is this formula used for? what is x(t)?i know that Vi= initial velocity, T= time) is x(0) equal to distance and height.
constant acceleration:
4.) a(t) = a(0) (<--- what does this mean?)
5.) v(t)= Vi + at (<--- what is v(t), and is this used to find the final velocity?)
6.) x(t) = Xi + ViT + 1/2at^2 (<--- what is this formula used for? what is it trying to find? what is x(t)? is x(0) equal to distance and height?)
and this formula, which i don't know what it's used for at all, but i know it's important:
Vf^2 = Vi^2 +2ad (d= distance traveled)
sorry for all the questions, but i think if i understand these formulas more, i would be able to do my physics homework easier, because i ALWAYS have trouble trying to find which formula to use.
