Can velocity be an imaginary number?
The main results showed that there is imaginary velocity if type of conics is hyperbola for �� = 0, but kinetic energy never be imaginary, only be negative value if �� = 0. Mean while, if types of conics is ellipse, then the velocity is real and kinetic energy always be positive.
What is imaginary time simplified?
Imaginary time is a mathematical simplification of time that is used in several equations across quantum mechanics and general relativity. What happened at the beginning of the universe? Most people would simplify and say that there was a Big Bang and then everything spontaneously burst into existence.
Can velocity be complex?
This suggests that the real and imaginary parts of a well-behaved function of the complex variable can be interpreted as the velocity potential and stream function, respectively, of some two-dimensional, irrotational, incompressible flow pattern.
What is imaginary time evolution?
For quantum many-body problems, an imaginary-time evolution method is a known computational method to identify the ground state. The imaginary-time evolution method selectively extracts the ground-state component by performing time evolution in the direction of imaginary time.
What is meant by two-dimensional flow?
Fluid motion can be said to be a two-dimensional flow when the flow velocity at every point is parallel to a fixed plane. The velocity at any point on a given normal to that fixed plane should be constant.
What is velocity and how is It measured?
Velocity is defined as a vectormeasurement of the rate and direction of motion. Put simply, velocity is the speed at which something moves in one direction. The speed of a car traveling north on a major freeway and the speed a rocket launching into space can both be measured using velocity.
What is an imaginary number anyway?

Imaginary numbers are based on the mathematical number i . From this 1 fact, we can derive a general formula for powers of i by looking at some examples.
How do you calculate constant velocity in physics?
You can calculate velocity by using a simple formula that includes rate, distance, and time. The most common way to calculate the constant velocity of an object moving in a straight line is with this formula: The SI (international) units for velocity are m/s (meters per second), but velocity may also be expressed in any units of distance per time.
What are the horizontal and vertical components of initial velocity?
Such a projectile begins its motion with a horizontal velocity of 25 m/s and a vertical velocity of 43 m/s. These are known as the horizontal and vertical components of the initial velocity.
