The angular velocity of the hour hand of length 1cm of a watch depends on the time unit and geometry of the watch. It can be calculated by dividing the angular displacement of the hour hand by time. One full rotation of the hour hand in 12 hours gives the angular velocity in radians per hour.
What else can I help you with?
What is the angular velocity of the hour hand of a clock?
Angular velocity = angle covered / time taken Hence angular velocity of the hour hand = 2pi/ 12*3600 = 1.4 x 10-4 rad/s
What is the magnitude of the acceleration experienced by the tip of the 1.7cm long sweep second hand on your wrist watch?
You are supposed to use one of the formulae for acceleration in circular motion. Use one of the following:a = v2/r, or:a = omega2rFirst you must convert everything to compatible units, for example meters, meters/second. Omega is the angular velocity and - if using SI units - should be converted to radians/second.
What is the direction of angular velocity?
The direction of angular velocity is perpendicular to the plane in which the rotation is occurring. It follows the right-hand rule, with the thumb pointing in the direction of the axis of rotation and the fingers curling in the direction of the angular velocity.
What is the Angular velocity of hour hand?
The angular velocity of the hour hand is 0.5 degrees per minute, because the hour hand completes a full rotation of 360 degrees in 12 hours.
What is the difference between angular velocity and angular momentum?
Angular velocity is a measure of how fast an object is rotating around a specific axis, usually measured in radians per second. Angular momentum, on the other hand, is a measure of how difficult it is to stop an object's rotation, calculated as the product of angular velocity and moment of inertia. In simple terms, angular velocity is the speed of rotation, while angular momentum is the rotational equivalent of linear momentum.
What is the angular velocity in radians per second of the second hand of a clock?
The angular velocity of the second hand of a clock is pi/30 radians per second.
What is the angular velocity of the hour hand of a clock?
Angular velocity = angle covered / time taken Hence angular velocity of the hour hand = 2pi/ 12*3600 = 1.4 x 10-4 rad/s
What is the difference betweentangential velocity or angular velocity?
angular velocity s the rotational analague of linear velocity...direction of linear velocity s along tangent to the circle while that of angulr velocity s along the axis of rotation.the direction of angular v can be find by right hand rule which state that if the axis of rotation s held n right hand with fingers curled round the direction of rotation then the thumb will mark the direction of angular velocity.... the magnitude of angular velocity that s the angular speed is represented by the length of the line along the axis of rotation...its units are rad/sec,degrees/sec or revolution/sec while that of linear velocity s m/sec...

What is Difference between angular velocity and angular speed?
Angular velocity refers to the rate of change of angular displacement with respect to time and has both magnitude and direction. Angular speed, on the other hand, refers to the rate of change of angular displacement with respect to time but does not consider direction and is scalar in nature. In simpler terms, angular velocity includes direction while angular speed does not.
What is the angular velocity of the minute hand?
The angular velocity of the minute hand can be calculated as 2π radians divided by the time it takes to complete one full revolution, which is 60 minutes. Therefore, the angular velocity of the minute hand is π/30 radians per minute.
What is the linear speed of the tip of the second hand of a watch with a length of 15 mm?
The second hand moves 1/60th of a full rotation per second, this is equivalent to 2π/60 radians per second this is known as the objects angular velocity. the equation linking linear velocity and angular velocity is v=rω where v=linear velocity, ω=angular velocity and r=radius and so we must substitute our values in. v=(15/1000)(π/30)=0.00157 m/s which is 1.57mm/s. notice instead of just putting 15 for the radius, i did 15/1000 in order to change it from millimetres to metres, this gave me the linear velocity in m/s.
How we find the Direction of angular velocity of a rotating wheel?
The direction of angular velocity in a rotating wheel can be found using the right-hand rule. If you curl your fingers in the direction the wheel is rotating, then your thumb points in the direction of the angular velocity vector. This rule helps determine whether the angular velocity is clockwise or counterclockwise relative to the rotation.
What is ment by angular momentum and angular velocity?
Angular velocity means how fast something rotates. The exact definition of angular momentum is a bit more complicated, but it is the rotational equivalent of linear momentum. It is the product of moment of inertia and angular speed.
