·2 A ball is being rotated in a circle of radius 5 m with a constant tangential velocity of 20 m/s A stone is also being rotated in a circle of radius 4 m with a constant tangential velocity of 16 m/s Which one of the following choices is true about both the circular motions a Both have same angular velocity b Both have different angular
Figure 1 illustrates angular distances a and relative angular position b As shown in the figure angular distances only give the magnitude of the angle between two lines regardless of the perspective On the other hand relative angular position requires lines 1 and 2 to be specifically identified the relative position of line 2 to line 1
A stone attached to one end of a string is whirled in a vertical circle The tension in the string is maximum when the string is horizontal; the string is vertical with the stone at highest position; the string makes an angle of 45 ∘ with the vertical; the string
·This change in angular velocity compensates for the change in angular momentum of the stone keeping the total angular momentum of the system constant 5 How is the Angular Momentum Stone Problem related to real world situations The Angular Momentum Stone Problem is a simplified thought experiment that helps understand the law of
Explore how circular motion relates to the bug s x y position velocity and acceleration using vectors or graphs Click to download the simulation Run using Java Assuming the kinetic coefficient of friction between steel and stone is calculate the angular acceleration of the grindstone b How many turns will the stone make
The angular position of a rod varies as 2 radians from time t = 0 The rod has two beads on it as shown in the following figure one at 10 cm from the rotation axis and the other at 20 cm from the rotation axis
6 The angular momentum L about point P is given by L = r × p where r is the position vector from point P to the stone and p is the linear momentum of the stone Now let s calculate the magnitude of the angular momentum L The position vector r is given by r = <d h> where d is the horizontal distance and h is the vertical displacement
·For those who don t know the G spot or Grafenberg spot is that magical area located about an inch inside the vaginal opening on the anterior front upper wall closest to your tummy

·Crushed stone often has an angular and jagged edge because of the crushing process Gravel on the other hand typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water Unlike crushed stone gravel is usually sold and used in its natural state If it is crushed gravel loses
·d Angular velocity of stone > angular velocity of ball Answer a Clarification Angular velocity = Tangential velocity/Radius When we put in the values and calculate the angular velocities for each of the circular motions we see that both the angular velocities are equal to each other and the value is 4 rad/s 6

stone weight N Fig The rod is rotated about end C so that the stone moves in a vertical circle of radius 85 cm The angular speed ω of the rod and stone is gradually increased from zero until the glue snaps The glue fixing the stone snaps when the tension in it is 18 N For the position of the stone at which the glue snaps
4 ·Kidney stone forms Kidney stones can form if urine becomes concentrated because there is not enough water in the allows crystals to form and attract other materials The creation of a kidney stone is not painful Stone leaves kidney The second stage of passing a kidney stone is when the stone has entered the tube that connects your kidneys to your
· Determination of Orbital Parameters from Angular positions Alone The traditional problem of celestial mechanics involves the determination of the orbital elements given the angular position on the celestial sphere at various times This information takes the form of pairs of celestial coordinates in some known coordinate system
This equation gives us the angular position of a rotating rigid body at any time t given the initial conditions initial angular position and initial angular velocity and the angular acceleration We can find an equation that is independent of time by solving for t in Equation ref{} and substituting into Equation ref{}
·Figure a We analyze two dimensional projectile motion by breaking it into two independent one dimensional motions along the vertical and horizontal axes b The horizontal motion is simple because a x = 0 a x = 0 and v x v x is thus constant c The velocity in the vertical direction begins to decrease as the object rises; at its highest point the vertical
Rotational Variables The angular position θ θ of a rotating body is the angle the body has rotated through in a fixed coordinate system which serves as a frame of reference ; The angular velocity of a rotating body about a fixed axis is defined as ω rad / s ω rad/s the rotational rate of the body in radians per instantaneous angular velocity of a rotating body ω
3 ·Explanation Angular velocity is the rate of change of angular displacement Here the angular velocity is 11 rad/s This implies that in one second the stone rotates by an angle of 11 rad Hence in s it will cover an angular displacement if rad
