MOVIMIENTO CIRCULAR UNIFORME

NUTACION

Nutation is a slight irregular movement on the axis of rotation of symmetrical objects that rotate on their axis.

Topic principal

velocity

TANGENTIAL VELOCITY

The tangential velocity is equal to the angular velocity by radius. It is called tangential because it is tangent to the trajectory. The tangential velocity is a vector, which results from the vector product of the angular velocity vector (ω) by the position vector (r) referred to the point P.

LINEAR SPEED

Centripetal acceleration

Centripetal acceleration (also called normal acceleration), is the acceleration that determines the change of direction of velocity in bodies rotating or moving along curved trajectories. This acceleration is called centripetal because it is always directed towards the center of rotation.

Linear velocity. It is one whose direction is always tangent to the trajectory of the rotating particle. This velocity has direction perpendicular to the axis of rotation (i.e. the vector ω) to the centripetal acceleration and the vector radius.

The velocity is obtained from the position vector by tangecial derivation

ANGULAR VELOCITY

Angular velocity is a measure of rotational velocity. It is defined as the angle rotated by a unit of time and is designated by the Greek letter ω. Its unit in the International System is the radian per second (rad/s).

Period and frequency

Period

The period T represents the time needed for the mobile to complete a turn and is given by:

Therefore, the frequency is the inverse of the period:

Subtopic

Frequency

The frequency F measures the number of revolutions or turns completed by the mobile in the unit of time and is given by:

PRECES ION

Precession or precession motion nutation is the motion associated with the change of direction in space, which experiences the instantaneous axis of rotation of a body.

Chandler's wobble is a small variation on the Earth's axis of rotation, discovered by American astronomer Seth Carlo Chandler in 1891. This is a variation of 0.7 arcseconds over a period of 433 days.
