What is the axis rotation?
: the straight line through all fixed points of a rotating rigid body around which all other points of the body move in circles.
What is a longitudinal axis?
An imaginary line (one of the anatomical reference axes) running down the centre of the body perpendicular to the transverse plane, around which rotations in the transverse plane (e.g. a body spin during a pirouette) occur.
What are objects that rotate?
Planets are not the only round objects that rotate. Amusement park rides, such as Ferris wheels or carousels, also rotate. The Ferris wheel rotates around a horizontal axis, and the carousel rotates around a vertical one. Wheels on a car rotate around a strong horizontal bar called an axle.
What is a transverse axis?
Transverse axis refers to an axis that is transverse (side to side, relative to some defined “forward” direction). In particular: Transverse axis (aircraft) Transverse axis of a hyperbola, coincides with the semi-major axis.
What is it called when a shape is flipped across?
When we flip or reflect a shape, we usually describe it as being flipped or reflected across a line–the mirror line. The vocabulary we use in flipping a shape is a bit different from the what we use when describing reflections.
What does the Earth spin around an imaginary line called?
Earth spins around an imaginary line called what? The axis, or earth axis of rotation. It’s a line through the geographical North and South Poles.
What is the difference between a turn and a rotation?
The usual primary-grades vocabulary is a “turn” and the usual middle-grades vocabulary is “rotation”. In primary grades, we usually describe a turn by how much it has turned, and we describe those turns as a fraction of a whole turn–so you might see a shape that has been turned by 1/2 turn, or by 1/4 turn…
What affects the choice of line when cornering?
The position and direction of the next corner also affects the choice of line. For example, if the next bend is a left hander you’ll need to move over to the right hand side of the track, and thus will need to apex later and take a tighter, slower line.
