| contents | In this paper we derive and discuss the time it takes for a force to turn a velocity. More precisely, we derive the formula for the time $τ$ it takes a constant force that makes an angle $α$ with the initial velocity $\vec{v}(0)$ to have $\vec{v}(τ)$ get within an angle $θ<α$ of the force. We then show how the addition of a viscous force decreases $τ$ logarithmically. The result can be generalized to any vector quantity whose first time derivative is a constant. |
