The 20 questions
-
Which equation links final velocity v, initial velocity u, acceleration a and time t for constant acceleration?
- v = ut + 2at
- v = at/u
- v = u + at
- v = u - at^2
-
Which constant acceleration formula does NOT contain the time t?
- s = (1/2)(u + v)t
- s = ut + (1/2)at^2
- v^2 = u^2 + 2as
- v = u + at
-
Which formula gives the displacement s in terms of u, a and t for constant acceleration?
- s = ut + (1/2)at^2
- s = (u + a)t
- s = ut - (1/2)at^2
- s = vt + at^2
-
Which formula gives the displacement in terms of the average of the initial and final velocities and the time?
- s = (u - v)t
- s = (u + v)t
- s = (1/2)(u + v)t
- s = (1/2)(u - v)t^2
-
Which formula gives the displacement in terms of the final velocity v, acceleration a and time t?
- s = vt - (1/2)at^2
- s = vt + at^2
