What is the equation that relates distance traveled (s), initial velocity (u), acceleration (a), and time (t) for an object moving with uniform acceleration?
What is the equation that relates distance traveled (s), initial velocity (u), acceleration (a), and time (t) for an object moving with uniform acceleration?
- s = ut + ½ at^2 (correct)
- 2as = v^2 - u^2
- v = u + at
- None of the above
