WebWe know that angular speed = 2π/T, hence ω = 1.99 x 10 -7 radians /seconds. The angular speed of Earth is 1.99 x 10 -7 radians /seconds. Angular Speed Examples The Earth rotates once on its axis once every 24 hours. What is its angular speed? Solution: The angle traversed in one revolution is 2π. The time taken for this rotation is 24 hours. WebThat is: linear distance = radius × angular distance. And by definition, linear distance = linear speed × time = radius × angular speed × time. By the definition of torque: torque = radius × force. We can rearrange this to determine force = torque ÷ radius. These two values can be substituted into the definition of power:
