Question

Passenger in accelerating car feels pushed back due to:

RankGuru · Accepted Answer

1. **Inertial Perspective**: The car accelerates forward. Due to inertia, the passenger's body 'wants' to remain at rest. The seat has to push the passenger forward to make them accelerate with the car.
2. **Non-Inertial Perspective**: Inside the car (the accelerating frame), the passenger experiences a pseudo force $F_p = -m a_{car}$. Since the car accelerates forward, the pseudo force is directed backward. This makes the passenger feel like they are being pressed into the back of the seat.
