Ans. Angular speed and linear speed are two different measures of how fast an object is moving. Angular speed is the rate at which an object rotates or moves around an axis, measured in radians per second. Linear speed, on the other hand, is the rate at which an object moves along a straight line, measured in meters per second. The relationship between angular speed and linear speed depends on the radius of the circular path and can be calculated using the formula v = ωr, where v is the linear speed, ω is the angular speed, and r is the radius.
