If a suspended pendulum bob is accelerated (in a car, for example), if you're in the accelerating frame of reference, you will observe the fictitious force which appears to act on the bob (as you're in the accelerating frame, the bob is not 'moving' so to speak, so to establish equilibrium you introduce the fictitious force.
The bob is thus at an angle to the vertical, due to the fictious force in the accelerating frame, OR due to the acceleration in the inertial frame. If the bob performs small oscillations about the line the angle makes to the vertical, how would you go about finding the time period? Presumably it'd not just sqrt(l/g)
