Is this true?
[tex]\vec \omega \times r = \vec v[/tex]
[tex]\vec \omega \times r = \vec v[/tex]
Velocity is a measure of how fast an object is moving in a particular direction. It is a vector quantity, meaning it has both magnitude (speed) and direction.
Velocity is calculated by dividing the change in an object's position (displacement) by the change in time. This means that velocity is equal to the object's displacement divided by the time it took to travel that distance.
Angular acceleration is the rate at which an object's angular velocity changes over time. It is a measure of how quickly an object is rotating or changing its direction of rotation.
Angular acceleration and linear acceleration are related through the radius of rotation. The linear acceleration of an object is equal to the angular acceleration multiplied by the radius of rotation.
Tangential acceleration is the component of linear acceleration that is parallel to the object's direction of motion. Centripetal acceleration, on the other hand, is the component of acceleration that is perpendicular to the object's direction of motion and towards the center of rotation.
