Just enter initial velocity of the object, acceleration and displacement in the below boxes and tap on the calculate button to attain the exact velocity for the given values as the result.
Ex: 10, 167, 48, 34.5 or 90
Velocity Calculator (v = √(u² + 2as)): Feeling that calculating the final velocity is very difficult then you are wrong because this calculator tool makes it quite easy. This page is designed for those whose are looking for the manual procedure to solve the final velocity. Here, we have covered the needy information on what is the final velocity and its formula along with few solved example questions.
You need to follow the simple steps provided below carefully to get the final velocity value. The steps are as follows
Question: A car starts with a velocity of 4 m/s and accelerates with 2 m/s² and reaches 20 km from the starting point. What is the final velocity of the car?
Initial velocity u = 15 m/s
Acceleration a = 16 m/s²
Displacement s = 20 km
Final velocity = ?
Convert displacement into meters
Displacement = 20 * 1000 = 20,000 meters
Final velocity v = √(u² + 2as)
By substituting the given values
v = √(15² + 2 * 16 * 20,000)
= √(225 + 6,40,000)
∴ Final velocity of car is 800.14 m/s².
1. What is the formula to calculate velocity, when acceleration and displacement are given?
The formula to calculate the final velocity of a moving object, when you have initial velocity, acceleration and displacement is listed here
v = √(u² + 2as)
Where, v is the final velocity
u is initial velocity
a is acceleration and
s is displacement
2. How does acceleration affect velocity?
If the acceleration and velocity points in the same direction, then the speed of the object increases. If the acceleration points in the opposite direction of velocity, then the object is slowing down.
3. Can velocity be negative?
An object which moves in negative direction will have negative velocity. So, yes velocity can be negative.
4. Which is the best site that offers free handy Velocity Calculator?
onlinecalculator.guru is one of the best sites out of others that provides all types of physics concepts calculators for free to help you during assignments & homework. You can also find the free online Velocity Calculator from here and solve all your lengthy calculations easily.
