The formula for work done by a constant torque is W = τΔθ, where W is the work done in joules, τ is the torque in newton-meters, and Δθ is the angular displacement in radians.
The work done by a constant torque does not directly affect the angular speed. It is only one factor in determining the angular speed, along with the moment of inertia and the net torque.
The work done equation only calculates the amount of work done, not the angular speed. To find the angular speed, you would need to use the equation ω = Δθ/Δt, where ω is the angular speed in radians per second, Δθ is the angular displacement, and Δt is the time taken.
No, the work done equation does not directly give the angular velocity. To find the angular velocity, you can use the equation ω = Δθ/Δt or ω = v/r, where v is the linear velocity and r is the radius.
Besides work done, the angular speed is also affected by the moment of inertia and the net torque. The moment of inertia is a measure of an object's resistance to change in its rotation, while the net torque is the sum of all the torques acting on an object.
