Cars are three-dimensional objects that have a fixed position and velocity.
We cannot even suppose that the particle has a position and velocity that are known to God but are hidden from us.
Through the useof CNC machining, the computer can control exact position and velocity.
Instead of being able accurately to predict two quantities, position and velocity, one can predict only a single quantity, the wave function.
Even God is bound by the uncertainty principle and cannot know the position and velocity;
In order to predict the future position and velocity of a particle, its present position and velocity must be measured accurately.
It's literally true on the atomic level,where we cannot accurately measure both position and velocity at the same time.
In order to predict the future position and velocity of a particle, one has to be able to measure its present position and velocity accurately.
It gets t and X as input variables,where the elements of X are understood to be precisely the position and velocity of the object.
This would allow one to predict with certainty one combination of position and velocity- which is half of what one could predict according to Laplace's ideas.
Danny Carey of Tool(band)- uses 7 Synesthesia Mandala Drums,which sense strike position and velocity.
Until that time,classical physics had assumed that when a particle's position and velocity were known, its future trajectory could be calculated.
After measuring the position and velocity of each one as accurately as possible, you enter the data into a monstrous computer and let it do the calculations for you.
The uncertainty principle of quantummechanics implies that certain pairs of quantities, such as the position and velocity of a particle, cannot both be predicted with complete accuracy.
In Newtonian mechanics, the time evolution is obtained by computing the total force being exerted on each particle of the system, and from Newton's second law,the time-evolutions of both position and velocity are computed.
In classical mechanics, the state of a point particle at anygiven time is often described with position and velocity coordinates in the Lagrangian formalism, or with position and momentum coordinates in the Hamiltonian formalism.
Measurements made by the spacecraft were used to create the Hipparcos catalogue,which contains detailed position and velocity measurements of 100,000 stars in our neighbourhood.
If the time evolution of the system is deterministic,where the state at one instant uniquely determines its past and future position and velocity as a function of time, such a system has six degrees of freedom.
Internal forces depend only on the positions and velocities of the bodies themselves and are independent of external signals.
(i) We would need to know the positions and velocities of all the particles in the Universe at a given instant.
But maybe this is our mistake: maybe there are no positions and velocities, but only waves.
The idea suggested itself that one shouldwrite down the mechanical laws not as equations for the positions and velocities of the electrons but as equations for the frequencies and amplitudes of their Fourier expansion.
Knowledge about this burst of star formation comes courtesy of the European Space Agency's Gaia satellite,which monitors the positions and velocities of stars throughout our galaxy.
Quantum mechanics deals with this situation via a class of quantumtheories in which particles don't have well-defined positions and velocities but are represented by a wave.
The Laplace version of scientific determinism held that if we knew the positions and velocities of particles at one time, we could determine their positions and velocities at any time in the past or future.
If at one time, one knew the positions and velocities of all the particles in the universe, the laws of science should enable us to calculate their positions and velocities at any other time, past or future.
Laplace was, of course, right, but Newton on the other hand had based his theory on absolute space and absolute time and the positions and velocities of the particles were given with respect to this absolute coordinate system.
In other words, if at some instant you know the positions and velocities of every particle in the universe, you can use Newton's laws of motion to determine- at least in principle- their positions and velocities at any other prior or future time.
