# How to find final velocity

Velocity is an object’s speed in a particular direction. Mathematically, velocity is often described as the change in position over the change in time. This fundamental concept shows up in many basic physics problems. Which formula you use depends on what you know about the object, so read carefully to make sure you’ve chosen the right one.

Velocity is a thing’s speed in a specific direction. Mathematically, speed is frequently described as the shift in place over the shift in time. This basic concept shows up in several standard physics issues. Which formulation you use depends on what you really know more about the item, therefore read carefully to be certain that you’ve selected the best one.

## The formula

Final velocity = Vf = Vi + at

• a = acceleration     t = time

## Locating Velocity out of Acceleration

Know the speed formulation to get an accelerating object. We can explain this by multiplying time and acceleration, and adding the result to the first velocity:

• Vf = Vi + at, or “final velocity = initial velocity + (acceleration * time)”
• Initial velocity Vis sometimes written as V(“velocity at time 0”).

Multiply the acceleration from the shift in time. This will tell you just how much the speed increased (or Decreased) within this period of time.

Add the initial velocity. Provided that you understand the entire shift in the speed. Insert This into the initial speed of the item, and you’ve got your answer.

Establish the path of motion. Contrary to Speed, speed always comprises the management of motion. Make sure To incorporate this in your response.

Solve related issues. As Long as you understand the acceleration, and also the speed at any 1 stage With time, you may use this formulation to get the speed at any other time.
