centerline around which a body revolves, as the Earth’s axis of rotation
the center around which something rotates
a kinematic parameter that is used to describe the characteristics of the motion of one rigid body (body segment) relative to a reference rigid body (another body segment) - e
an imaginary line around which a celestial body spins. Most of the planets tend to have their axis perpendicular to the ecliptic, bot not all of them
An imaginary line about which rotation occurs.
The distance between the translational energy and the rotational energy. In English, the amount of axis tilt that a bowler has.
The vertical axis around which the crane's superstructure rotates.
in a rotating object, the axis of rotation is the line about which the object is turning. The axis of rotation for a spinning record is its middle. The reference point for angular momentum is often chosen to be along the axis of rotation.
The axis of rotation (spin axis) is that straight line about which a body rotates.
(example, 0, 45, and 90 degrees) This is a measure of the direction of the initial rotation on the ball with respect to the lane. It is a measurement of the angle between the initial spin axis and the foul line running across the lane. A zero degree axis of rotation is all forward roll. The rotation on the ball is in the direction of the forward travel. The rotation will help keep the ball in the initial direction. The ball will not hook very much. It will roll out early. Therefore, a bowler with this style will need balls drilled to go long. A 90-degree axis of rotation is all side roll. The rotation is perpendicular to the initial direction. The rotation is trying to make the ball hook at a 90-degree angle to the initial direction. This gives the ball more potential to hook. This style causes the ball to skid further down the lane and then hook more. A bowler with this style will most likely need balls drilled to hook earlier; such as, axis weight or pins closer to their axis.
An imaginary line, perpendicular to the track, along which a bowling ball rotates.
The line that every particle in the rotating rigid body circles about.
