The correct answer is backwards.

Key Points Inertia and Newton's First Law:

• The tendency to fall backward is explained by Newton's first law of motion, also known as the law of inertia.
• Inertia is the tendency of an object to resist changes in  its state of motion.  
• When the bus is at rest, your body is also at rest.
• When the bus suddenly accelerates forward, your feet, which are in contact with the bus floor, move forward with the bus.
• However, the upper part of your body tends to remain at rest due to inertia.
• This difference in motion between your feet and upper body causes you to lean backward.
• Your feet are experiencing the force of the bus's acceleration, while your upper body resists this force.
• The upper part of your body tries to maintain its original state of rest.
• The muscles in your body work to counteract this effect and maintain your balance.
• The sudden change in motion creates an imbalance, leading to the backward lean.
• The faster the acceleration of the bus, the greater the tendency to fall backward.
• This phenomenon is a common experience and a direct result of inertia.
• The effect is more pronounced when the bus accelerates rapidly.
• The concept of inertia applies to all objects, not just human bodies.
• This is an example of how forces and motion interact in everyday situations.
• The backward lean is a temporary effect, as your body eventually adjusts to the new motion.
• If you were holding onto a railing or seat, the effect would be less pronounced.
• The force of friction between your feet and the bus floor also plays a role in your movement.
• The center of mass of your body also influences your stability during this movement.
• The human body's balancing mechanisms are designed to counteract such forces.
• This situation demonstrates the fundamental principle that objects resist changes to their current state of motion.
• This is a real world example of how inertia effects the human body.
