  2. In mathematical terms, uniform acceleration is defined by the equation: a = Δv Δt a = Δ v Δ t. Here, Δv Δ v represents the change in velocity, and Δt Δ t denotes the change in time. Characteristics of Uniform Acceleration. Understanding the nuances of uniform acceleration becomes easier when we delve into its core characteristics.

  3. Uniform Acceleration Equations. When we are talking about motion in a straight line with constant acceleration, there are three equations of motion, which are helpful in determining one of the unknown parameters: \ (\begin {array} {l}v = u + at\end {array} \) \ (\begin {array} {l}x = ut + \frac {1} {2}at^ {2} \end {array} \)

  4. Since the acceleration is uniform, there is no need to use calculus to derive these. The first follows immediately from the meaning of acceleration. Distance travelled is the area under a speed : time graph.

  5. Use our revision notes to learn how to apply the uniform acceleration equation v² = u² + 2as. Learn more.

  6. When we have two speeds we can calculate the acceleration during the time interval, t, by subtracting the initial speed from the final speed ( we get the change in speed ) and then dividing by the time to get the acceleration.

  7. Feb 5, 2013 · Acceleration that does not change in time is called uniform or constant acceleration. The velocity at the beginning of the time interval is called initial velocity, vi, and the velocity at the end of the time interval is called final velocity, vf.
