Initial Velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts. They are four initial velocity formulas: (1) If time, acceleration and final velocity are provided, the initial velocity is articulated as. u = v – at.
May 20, 2024 · What formulas are used to find initial velocity? If you have values for the final velocity, acceleration, and time involved, use Vi = Vf - (a * t). If you know values for the distance, time, and acceleration, use Vi = (d / t) - [ (a * t) / 2]. If you're given the final velocity, acceleration, and distance, use Vi = √ [Vf2 - (2 * a * d)].
Initial velocity can be formulated in a unit of a meter per second i.e. ms−1. Solved Examples. Q.1: A train is moving through a city with a slow speed. Once outside the city, the train accelerates at 0.40 ms−2 for 60.0 s. After this acceleration, the velocity of the train is 30.0 ms−1.
Sep 12, 2023 · The initial velocity formula is derived from the equations of motion, which describe the motion of an object over time. These equations are based on Newton’s laws of motion, which establish the relationship between force, mass, and acceleration. The equations of motion are: v = u + at. s = ut + 1/2 at^2. v^2 = u^2 + 2as.
Apr 14, 2023 · Initial Velocity Formula. There are three formulas based on the concept of initial velocity: 1.u = v - at. This equation describes how velocity changes over time under constant acceleration. 2. u2 =v2 − 2as u 2 = v 2 − 2 a s.
Apr 18, 2024 · Simple velocity equation: velocity = distance / time. Velocity after a certain time of acceleration: final velocity = initial velocity + acceleration × time. Average velocity formula — the weighted average of velocities: average velocity = (velocity₁ × time₁ + velocity₂ × time₂ + …) / total time
Jun 8, 2024 · The first formula to find initial velocity is u = v – at. The Second Formula is: u = s/t – ½ at where ‘s’ = displacement travelled within the time period ‘t’.
