Is force dependent on velocity?
The viscous force that a fluid exerts on a particle depends on velocity, F = F(v). For most problems, it suffices to expand F in powers of v and keep only the 1st and 2nd orders: F(v) = −c1v − c2v|v| − c3v3 − Note: These coefficients depend on shape.
What is the other meaning of velocity?
quickness of motion
Definition of velocity 1a : quickness of motion : speed the velocity of sound. b : rapidity of movement [my horse’s] strong suit is grace & personal comeliness, rather than velocity— Mark Twain. c : speed imparted to something the power pitcher relies on velocity— Tony Scherman.
What is the other name of Coriolis force?
Coriolis force, also called Coriolis effect, in classical mechanics, an inertial force described by the 19th-century French engineer-mathematician Gustave-Gaspard Coriolis in 1835.
Which is velocity dependent?
In the velocity-dependent case, forces are directed like the velocity vector (B−) or in the opposite direction (B+). Force magnitude is greater at peak speed.
Which force is velocity dependent but conservative?
Note that the velocity-dependent Lorentz force is conservative since E is conservative, and because (v×B×v)dt=0, therefore the magnetic force does no work since it is perpendicular to the trajectory.
Which word is similar to velocity?
In this page you can discover 36 synonyms, antonyms, idiomatic expressions, and related words for velocity, like: speed, quickness, rate, acceleration, motion, swiftness, expedition, clip, acceleration speed, escape-velocity and haste.
What is velocity in a simple definition?
Definition of velocity rapidity of motion or operation; swiftness; speed: a high wind velocity. Mechanics. the time rate of change of position of a body in a specified direction. the rate of speed with which something happens; rapidity of action or reaction.
What are Coriolis and centrifugal force?
The Centrifugal Force is proportional to the square of the rotation rate. The Coriolis Force is proportional to the rotation rate. The Centrifugal Force is related to the body’s distance from the rotating frame’s axis. The Coriolis Force is proportionate with the velocity vector that is orthogonal to the rotation axis.
What is Coriolis force?
The Coriolis force applies to movement on rotating objects. It is determined by the mass of the object and the object’s rate of rotation. The Coriolis force is perpendicular to the object’s axis. The Earth spins on its axis from west to east. The Coriolis force, therefore, acts in a north-south direction.
Which force is velocity dependent conservative?
Is velocity dependent on direction?
Velocity is a physical vector quantity; both magnitude and direction are needed to define it.
Can a conservative force depend on velocity?
To be conservative, F must be a function of position only: forces that depend on velocity, time, etc. cannot be conservative.
What is the meaning of velocity in science?
Velocity defines the direction of the movement of the body or the object. Speed is primarily a scalar quantity. Velocity is essentially a vector quantity. It is the rate of change of distance. It is the rate of change of displacement.
What is a synonym for net force?
The net force on a body applied at a single point with the appropriate torque is known as the resultant force and torque.
Is speed synonymous with velocity?
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.
How do you describe the velocity of an object?
Velocity is a vector quantity that refers to “the rate at which an object changes its position.” Imagine a person moving rapidly – one step forward and one step back – always returning to the original starting position. While this might result in a frenzy of activity, it would result in a zero velocity.
What is Coriolis component of acceleration in polar coordinate system?
Coriolis acceleration is the acceleration due to the rotation of the earth, experienced by particles (water parcels, for example) moving along the earth’s surface. Ocean currents are influenced by Coriolis acceleration.
What is the difference between centrifugal acceleration and Coriolis acceleration?
Which is velocity-dependent?
