Enter the initial velocity, time, and distance into the calculator to determine the final horizontal velocity.

Final Horizontal Velocity Formula

The following equation is used to calculate the Final Horizontal Velocity.

Vf = D/T*2 - Vi
  • Where Vf is the final horizontal velocity (m/s)
  • D is the distance traveled (m)
  • T is the time (s)
  • Vi is the initial horizontal velocity (m/s)

To calculate the final horizontal velocity, divide the distance by the time, multiply by 2, then subtract the initial velocity.

What is a Final Horizontal Velocity?

Definition:

A final horizontal velocity is a measure of the velocity of an object after it has undergone either acceleration or deceleration.

How to Calculate Final Horizontal Velocity?

Example Problem:

The following example outlines the steps and information needed to calculate Final Horizontal Velocity.

First, determine the distance traveled. In this example, the distance traveled is found to be 500 m.

Next, determine the time. For this problem, the time is found to be 20 seconds.

Next, determine the initial horizontal velocity. In this case, the initial horizontal velocity is measured to be 20 m/s.

Finally, calculate the Final Horizontal Velocity using the formula above:

Vf = D/T*2 – Vi

Vf = 500/20*2 – 20

Vf = 30 m/s

FAQ

What factors can affect the final horizontal velocity of an object?

Several factors can affect the final horizontal velocity of an object, including air resistance, the object’s mass, the angle of projection (in cases where the motion is not strictly horizontal), and any forces applied to the object during its motion.

How does air resistance impact the calculation of final horizontal velocity?

Air resistance can slow down an object moving through the air, reducing its final horizontal velocity. The effect of air resistance is not accounted for in the basic formula provided, which assumes motion in a vacuum or neglects air resistance for simplicity. For more accurate calculations involving air resistance, more complex physics equations are needed.

Can the formula for final horizontal velocity be used for objects in free fall?

The formula provided specifically calculates the final horizontal velocity, assuming constant horizontal motion without the influence of external forces like gravity on the horizontal component. For objects in free fall, or projectiles, the vertical component of motion is significantly affected by gravity, but the horizontal component can still be calculated using this formula if the horizontal motion is considered separately and is not influenced by other forces.
