It is because of Newtons first law of inertia. When the bus moves forward your body is inclined to stay in the same position, so it is as if the floor is moving out from under your feet.
When a car accelerates, it pushes you back due to inertia. Inertia is the tendency of an object to resist changes in its motion, so as the car speeds up, your body wants to stay at rest causing you to move backward in relation to the direction of acceleration.
Passengers on a bus tend to fall backward when it starts suddenly due to inertia. As the bus accelerates forward, the passengers, who were initially at rest, want to stay at rest due to their inertia. This causes them to lean back or fall backward as the bus moves forward.
Free fall from rest typically refers to an object falling under the influence of gravity without any initial velocity. This means that the object starts falling from a stationary position and solely accelerates due to gravity without any other forces acting on it. Objects in free fall from rest will accelerate at a rate of approximately 9.81 m/s^2 on Earth.
If an object is released from rest and falls at rest in the absence of friction, it means that the object is in free fall. During this process, the object accelerates due to the force of gravity until it reaches its terminal velocity when air resistance equals the gravitational force acting on the object.
Passengers fall backward when a bus starts suddenly because of inertia. Inertia is the tendency of objects to resist changes in their state of motion. When the bus accelerates forward, the passengers' bodies want to stay at rest due to inertia, causing them to fall backward.
Imagine that you are standing inside a stationary bus. Suddenly the bus starts moving and you fall backwards. This is due to the inertia of your body. When the bus was at rest, you were also at rest. When the bus started moving, your legs went with the floor of the bus due to friction. But the upper part of your body tends to continue in its state of rest (inertia of rest). As a result you fall backwards.

The force accelerates the body, a=F/m.

The second car accelerates
Passengers fall backward when a bus starts suddenly because of inertia. Inertia is the tendency of objects to resist changes in their state of motion. When the bus accelerates forward, the passengers' bodies want to stay at rest due to inertia, causing them to fall backward.
because the bus still moving its uniform motion suddenly the bus applies brakes the bus stop at rest so we fall forward due to inertia and the bus was its rest suddenly the bus starts its accelerates so we fall backwards due to inertia
30m/s
The package on the seat slides backward because of inertia. As the bus accelerates forward, the package wants to remain at rest (due to its initial inertia), causing it to move in the opposite direction of the bus's acceleration. This results in the package sliding backward relative to the bus.
The distance a car travels when it starts from rest and accelerates to a certain speed depends on the acceleration of the car and the time it takes to reach that speed. The formula to calculate this distance is d 0.5 a t2, where d is the distance, a is the acceleration, and t is the time taken to reach the speed.
