Pseudo Force (intuition)
Mediumphysics
Passenger in accelerating car feels pushed back due to:
Select the correct option:
Solution
Incorrect! Answer:
Backward pseudo force
- 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.
- Non-Inertial Perspective: Inside the car (the accelerating frame), the passenger experiences a pseudo force Fp=−macar. 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.
