Use this velocity calculator to determine the velocity of an object based on the distance and time taken to cover it. In addition to this, our calculator allows you to make the following calculations:
“Velocity describes how fast an object moves in a particular direction over time”
It is a vector quantity that has both magnitude and direction but this is different from speed which only describes how fast something is moving without direction.
\(Velocity = \dfrac{Displacement}{Time}\)
or
\(v = \dfrac{d}{t}\)
Here our velocity calculator also takes displacement and time values to automatically calculate the velocity in terms of different units.
Unit | Equivalent in km/h |
---|---|
km/h | 1.0000 |
knot | 1.8520 |
ft/s | 0.3048 |
ft/min | 0.0051 |
cm/s | 0.0036 |
in/s | 0.0254 |
m/h | 0.2778 |
mph | 1.6093 |
yd/s | 0.9144 |
Speed of light (c) | 299,792,458 m/s (constant, not a unit) |
To calculate the velocity of any object moving under constant acceleration, you can follow the given steps and take a look at the example:
\(v = \frac {d}{t}\)
If a train covers a displacement of 100km in an hour, its velocity will be:
Step 1 – Convert units to the smallest value
Distance = 100km = 100 * 1000 = 100,000 meter
Time = 1 hour = 60 * 60 seconds = 3600 seconds
Step 2 – Calculate velocity
Velocity (v) = Displacement (d) / Time (t)
Velocity (v) = 100000/3600
Velocity (v) = 27.777 \(ms^{-1}\)
Along with velocity, you can also find the initial, final, and constant speed of an object in a particular direction using this online velocity calculator.
Velocity is the rate at which an object changes its position in a specific direction, while speed is the rate of measuring how quickly an object moves.
For example, a cycle rider covers a distance of 10km/hr along a road. If we describe in a straight path that cycle rider travelling in a west direction, that is its velocity.
There are several industries and cases where a velocity calculator can be used:
According to Newton’s 1st law of motion, Force is the major parameter that causes a change in either speed or direction. Thus, it causes a change in velocity. The velocity calculator can also figure out how a change in force affects the motion of an object by determining the final velocity.
Yes, velocity can also be negative when an object travels in a direction opposite of positive.
Suppose you have east as a positive direction, then a velocity of -20 m/s means the object is moving 20 m/s westward.
External forces can greatly affect the velocity of objects. These forces can arise in multiple cases, including:
It’s nearly impossible to find velocity without time, as the value depends upon the distance traveled over time. However, there are certain situations in which you can use other values alongside displacement to solve for velocity.
For example, if you have constant acceleration and displacement values, you can use the following equation of motion to determine velocity:
v^2 = u^2 + 2as
where:
If a car moves at a velocity of 150 meters per second in the east direction, its speed will be:
Speed = |Velocity|
Speed = |150 metres per second|
Speed = 150 meters per second (Magnitude only)
