# Instantaneous Velocity Calculator

The Instantaneous Velocity Calculator is a free web tool that calculates the instantaneous velocity given a displacement and time. This Instantaneous Velocity Calculator tool speeds up the calculation by displaying the instantaneous velocity in a fraction of a second.

### What is instantaneous velocity and how does it work

The instantaneous velocity of an object is defined as its velocity at a specific point in time. It's a quantity with a vector. The instantaneous velocity is the velocity of an item in motion at a specific point in time. m/s is the SI unit for representing instantaneous velocity.

This kind of velocity of an object in motion is instantaneous velocity. This can be calculated as the average velocity, but we can reduce the time period to get it closer to zero. A moving object's average and instantaneous velocities may be the same if it has a constant velocity over time. With examples, we will go over the instantaneous velocity formula in this article.

The limit of the average velocity as the elapsed time approaches zero, or the derivative of x with respect to t, is the instantaneous velocity of an object:

v(t) = (d/dt)x(t)

Also,**V _{int} = dx/dt**

- Where, V
_{int}is the instantaneous velocity. - dt be the change in time

### What method do you use to calculate instantaneous velocity?

The following is steps on how to find the instantaneous velocity.

- Find an equation that represents the change in distance (x) as a function of time (t).
- Differentiate the formula according to the passage of time.
- Assume that dx/dt is the instantaneous velocity.
- In the differentiated formula, enter the desired time. The instantaneous speed at time t is the result.

### Instantaneous Velocity Example

**Question 1:** What is the Instantaneous Velocity of a particle travelling in a straight line for 5 seconds with a position function x of 6t^{2}+4t+2?

**Solution:**

Consider the problem, we have

x = 6t^{2}+4t+2

We can derive Instantaneous Velocity by differentiating the provided function with respect to t as follows: V_{int}=dx/dt

By substituting the function x,

V_{int}=d/dt(6t^{2}+4t+2)

V_{int}=12t+4

Put value of t= 5, we get

V_{int}=12*5+4

V_{int}=64 ms^{−1}

Resolution = 4.066667*10^{-09} radian

Thus, The Instantaneous Velocity of a particle travelling in a straight line for 5 seconds is **64 ms ^{−1}**

### FAQs on Instantaneous Velocity Calculator

**1. What causes a velocity change?**

The velocity of an object changes as it interacts with other objects. When a travelling item collides with another object in its path, it will either slow down (if it collides with something smaller, such as an air particle) or stop (if it collides with something larger, such as a wall) (if it hits a wall).

**2. What is instantaneous velocity?**

The instantaneous velocity is sometimes known as simply velocity, is a quantity that tells us how fast an object is going somewhere along its route.

**3. Is instantaneous velocity and acceleration the same thing?**

No, they're not the same thing because as an object's distance (s) changes over time, its velocity is defined as the rate at which the distance changes in relation to time, whereas its acceleration is defined as the rate at which the velocity changes in relation to time.

**4. What is velocity?**

Velocity is the rate and direction at which an object moves, whereas acceleration is the rate at which that object's speed changes over time. The units of velocity is m/s.

**5. What does Instantaneous Velocity Mean?**

The instantaneous velocity of an object is defined as its velocity at a specific point in time. It's a quantity with a vector.
