Acceleration is defined as the rate change of position true or false?

Acceleration (ack-sell-uh-RAY-shun) is can be absolute, angular, and coriolis. All three are accelerations because they change position/speed over time. Velocity is a measure of distance moved over time. Acceleration is velocity that is changing (speeding up or slowing down, or changing direction) Absolute: The speed continually changes. (A car speeding up) Angular: The direction continually changes. (A planet circling the Sun in orbit) Coriolis: A combination of the above, where a particle changes its distance (absolute) to the center of a whirling mass (Angular).


A wheel of point 6 m in diameter is rotating at 100 rad per sec The wheel then decelerates uniformly from 100 rad per sec to 50 rad per sec in 50 revolutions Determine the rate of angular acceleration?

Angular acceleration is got by the expression alpha = {(final angular velocity)2 - (initial ang velocity)2} / 2 theta. final is 50 and initial is 100 rad/s. Theta is 50 x 2pi radian Therefore required alpha = -50 x 150/200 pi = -75/2pi radian/s2 Negative sign indicates that the rotation is decelrated.

Relation between angular velocity and linear velocity?

Angular velocity is the rate of change of an object's angular position with respect to time, while linear velocity is the rate of change of an object's linear position with respect to time. The relationship between angular velocity and linear velocity depends on the distance of the object from the axis of rotation. For an object rotating around a fixed axis, the linear velocity is equal to the angular velocity multiplied by the radius of the rotation.


What is the derivative of angular velocity and how is it calculated?

The derivative of angular velocity is angular acceleration. It is calculated by taking the derivative of the angular velocity function with respect to time. Mathematically, angular acceleration () is calculated as the rate of change of angular velocity () over time.


What is the relationship between velocity (v), angular velocity (w), and radius (r) in the context of rotational motion?

In rotational motion, velocity (v) is related to angular velocity (w) and radius (r) through the equation v w r. This means that the linear velocity of a point on a rotating object is equal to the product of the angular velocity and the distance from the center of rotation (radius).


How can one determine the angular acceleration when provided with the angular velocity?

To determine the angular acceleration when given the angular velocity, you can use the formula: angular acceleration change in angular velocity / change in time. This formula calculates how quickly the angular velocity is changing over a specific period of time.


How to convert Angular velocity to velocity?

To convert angular velocity to linear velocity, you can use the formula: linear velocity = angular velocity * radius. This formula accounts for the fact that linear velocity is the distance traveled per unit time (similar to speed), while angular velocity is the rate of change of angular position. By multiplying angular velocity by the radius of the rotating object, you can calculate the linear velocity at the point of interest on that object.


Relation between linear velocity and angular velocity?

Linear velocity is directly proportional to the radius at which the object is moving and the angular velocity of the object. The equation that represents this relationship is v = rω, where v is the linear velocity, r is the radius, and ω is the angular velocity. As the angular velocity increases, the linear velocity also increases, given the same radius.


How can one calculate angular velocity from linear velocity?

To calculate angular velocity from linear velocity, you can use the formula: Angular velocity Linear velocity / Radius. This formula relates the speed of an object moving in a circular path (angular velocity) to its linear speed and the radius of the circle it is moving in.
