When the bus comes to an immediate stop, your body tends to remain in motion due to inertia, not because of an external force acting in the direction of motion. This is a consequence of Newton's first law of motion, which states that an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced external force. In this scenario, there is no forward force being applied to you when you slide forward; instead, it's the lack of force to keep you stationary with the bus that causes you to slide forward.
