Curvature also plays a key role in physics. The magnitude of a force required to move an object at constant speed along a curved path is, according to Newton's laws, a constant multiple of the curvature of the trajectories. Use |F| = m|a| IF|=m|a| and the decomposition of acceleration into tangential and normal components to choose the answer choice below that correctly expresses the above statement as a mathematical equation.
