Since the magnetic Lorentz force is always perpendicular to the magnetic field, it has no influence (to lowest order) on the parallel motion. In a uniform field with no additional forces, a charged particle will gyrate around the magnetic field according to the perpendicular component of its velocity and drift parallel to the field according to its initial parallel velocity, resulting in a ...
The force is perpendicular to the relative direction of motion and oriented towards the direction of rotation, i.e. the direction the "nose" of the ball is turning towards. [7] The magnitude of the force depends primarily on the rotation rate, the relative velocity, and the geometry of the body; the magnitude also depends upon the body's ...
The rigid body's motion is entirely determined by the motion of its inertia ellipsoid, which is rigidly fixed to the rigid body like a coordinate frame. Its inertia ellipsoid rolls, without slipping, on the invariable plane , with the center of the ellipsoid a constant height above the plane.
The equation of motion of a fluid on a streamline for a flow in a vertical plane is ... is related to the pressure gradient acting perpendicular to the streamline ...
Instead of flowing down the gradient, large scale motions in the atmosphere and ocean tend to occur perpendicular to the pressure gradient. This is known as geostrophic flow . [ 39 ] On a non-rotating planet, fluid would flow along the straightest possible line, quickly eliminating pressure gradients.
In fluid mechanics, simple shear is a special case of deformation where only one component of velocity vectors has a non-zero value: = (,) = = And the gradient of velocity is constant and perpendicular to the velocity itself:
In words, the stream function is the volumetric flux through the test surface per unit thickness, where thickness is measured perpendicular to the plane of flow. The point is a reference point that defines where the stream function is identically zero. Its position is chosen more or less arbitrarily and, once chosen, typically remains fixed.
Lift is the component of this force that is perpendicular to the oncoming flow direction. [1] It contrasts with the drag force, which is the component of the force parallel to the flow direction. Lift conventionally acts in an upward direction in order to counter the force of gravity , but it is defined to act perpendicular to the flow and ...
