The first one relies on the basic velocity definition that uses the well-known velocity equation. The second method calculates what is velocity change caused by acceleration over a specific time interval. Finally, the third part of the velocity calculator makes use of the average velocity formula, which may be useful if you need to analyze journeys with various velocities over different distances.
Escape velocity is the minimum speed an object needs to escape another objects gravitational pull. The most common example of this is the speed a spacecraft requires to leave Earth for distant planets, which is approximately 11.2 km/s.
Velocity is the speed and direction with which an object is moving, while acceleration is how the speed of that object changes with time. The units for velocity are m/s, while for acceleration they are m/s 2.
Interactions with other objects cause velocity to change. When a moving object collides with another object in its path, it will slow down (if it collides with something smaller, e.g. an air particle) or stop (if it hits a wall). If an object expels matter behind it, it will speed up, like a rocket. An object will also accelerate towards other objects via gravity.
Terminal velocity occurs in fluids (e.g., air or water) and depends on the fluid's density. You can read more about it in our free fall with air resistance calculator. Knowing how to calculate velocity is of particular importance in astrophysics since results have to be very accurate.
The average velocity formula describes the relationship between the length of your route and the time it takes to travel. For example, if you drive a car for a distance of 70 miles in one hour, your average velocity equals 70 mph. In the previous section, we have introduced the basic velocity equation, but as you probably have already realized, there are more equations in the velocity calculator. Let's list and organize them below:
It will take the average human approximately 15 seconds to reach 99% of terminal velocity with their belly facing the Earth. Reach 100% terminal velocity is very difficult, if not impossible, as acceleration drops exponentially as an object approaches its terminal velocity.
The circular velocity of an object is calculated by dividing the circumference of the circular path by the time period over which the object travels.
Multiply the acceleration by the change in time. This will tell you how much the velocity increased (or decreased) over this time period.
Average velocity measures the average velocity an object travels over the full course of its path. Instantaneous velocity measures the velocity of an object at a specific moment along its path.
To find the velocity, use the equation: Final velocity = initial velocity + (acceleration due to gravity) (time).
In order to find the velocity of the moving object, you will need to divide the change in position by the change in time. Specify the direction moved, and you have the average velocity.
velocity = distance/time. As the distance increases, the velocity also increases.
Divide distance traveled by the time taken to get the average speed. Velocity is the term used for speed when the object travels in a uniform direction (i.e. straight line or circle).
