Easily calculate final velocity online with our free Final Velocity Calculator. Use Vi, a, and t to find Vf instantly with step-by-step results.
Understanding how an object moves is one of the foundations of physics. Velocity plays a major role in predicting the motion of objects in real life, from a ball rolling on the ground to a car speeding up on the highway. To make this easier, we have developed a Final Velocity Calculator. With this tool, you can quickly determine the final velocity of a moving object using the standard kinematics formula.
The calculator is simple to use, accurate, and designed for students, teachers, and anyone interested in physics.
Final velocity is the speed and direction of a moving object after it has accelerated over a certain period of time. If an object starts with an initial velocity, experiences acceleration, and continues for some time, the final velocity is the result of that motion.
In simple terms, it answers the question: “How fast is the object moving now after acceleration?”
The formula used to calculate final velocity is:
Vf = Vi + a × t
Where:
Typical units include meters per second (m/s) for velocity, meters per second squared (m/s²) for acceleration, and seconds (s) for time. You can also use other units such as kilometers per hour or feet per second as long as they are consistent.
The calculator will automatically handle unit conversions and give you the result in your selected velocity unit.
Let’s go through an example to understand this better.
An object starts with an initial velocity of 50 m/s. It accelerates at 5 m/s² for 5 seconds.
Using the formula:
Vf = Vi + a × t
Vf = 50 + (5 × 5)
Vf = 75 m/s
So, the final velocity of the object is 75 m/s.
Our Final Velocity Calculator is a handy tool for solving motion problems without struggling through manual calculations. Whether you want to know how far you fall in 2 seconds, how to calculate Vf and Vi, or even check how a ball can travel 9 m at a velocity of 6 m/s, this calculator makes the process easy.
It is perfect for physics students, teachers, and anyone curious about motion in real life. With step-by-step results and instant answers, you can save time and improve accuracy in your learning.
You calculate final velocity using the formula Vf = Vi + a × t, where you add the product of acceleration and time to the initial velocity.
If you drop an object, it accelerates due to gravity (9.8 m/s²). After 2 seconds, the final velocity would be:
Vf = 0 + (9.8 × 2) = 19.6 m/s.
This depends on the average velocity and the time of travel. Even if the final velocity was 6 m/s, the ball’s average velocity over the motion could cover 9 m.
To calculate Vf, use the formula Vf = Vi + a × t. To find Vi, rearrange the formula as Vi = Vf – a × t.
