At a given rotational speed how does linear speed change its distance from the axis changes?

In The Center Of The Rotating Platform Right At Its Axis You Have No Linear Speed At All, But You Do Have Rotational Speed. Your Rotational Speed would Stay The Same But As You Move Away From The Center Your Linear Speed Gets Faster And Faster. If You Move Twice As Much From The Center Your Linear (Tangential) Speed Would Also Be Twice as Much

What is the relationship between rotational speed and linear speed?
(linear speed) = (rotational speed) x (radius or distance from the center) To use consistent measures, use radians/second for rotational speed, meters for the radius, and meters/second for the linear speed. If you know rotational speed in some other unit - for example, rpm (rotations per minute) - convert to radians per second first.
What is the rotational analog of force in linear motion?
The rotational analog of force in linear motion is "Torque".
Why fan blades are slightly bent?
That bend is needed in order to change rotational motion of the blades into the linear motion of moving air.
What is the rotational analog of mass in linear motion?
That is called moment of inertia.
What is torque and state the conditions of rotational equilibrium?
Torque is analogous to force. As Force produces a change in the state of linear motion of a body, Torque produces a change in the state of rotational motion of a body. The unit is newton meter (Nm) and the symbol is tau (τ) For rotational equilibrium, the algebraic sum of the torques acting on a body must be zero. ie. Στ=0
How does linear speed change as rotational speed changes?
At any distance from the axis of rotation, the linear speed of an object is directly proportional to the rotational speed. If the linear speed increases, the rotational speed also increases.
How does rotational speed cange as an object moves away from the axis?
The rotational Speed or angular velocity of an object does not change even if they move away from the axis, however its linear velocity changes.

How is a pulley important?
Pulleys are used to change the direction of an applied force, transmit rotational motion, or realize a mechanical advantage in either a linear or rotational system of motion.
What is 1 meter per second in rpm?
Linear speed cannot be converted to rotational speed without knowledge about the distance from the axis of rotation.
Why fan blades are slightly bent?
That bend is needed in order to change rotational motion of the blades into the linear motion of moving air.
What are the two basic kinds of kinetic energy?
Linear and rotational
Does a pulley convert linear force to a rotational motion?
YES
What is the unit of tangential speed and linear speed?
Tangential speed is how fast a point on a circular object is moving at a certain distance from the center whereas rotational speed is how many degrees (or radians) a point on the circle goes through in a period of time. Every point on a circle has the same rotational speed. The further out you go from the center, the higher the tangential speed is.
What type of energy do motors change electrical energy into?
Most electric motors change electrical energy into rotational mechanical energy. A few electric motors change electrical energy into linear mechanical energy.
