What physics is involved for a passenger feeling pushed backward into the seat of an airplane when it accelerates along the runway during takeoff?
Solution 8E Step 1 The reason for the the passenger is being pushed backward to his seat during the takeoff of an aeroplane is the inertia. According to Newton’s 1st law of motion, every body will continue in its state of rest or uniform motion unless and until it is compelled by an external unbalanced force. So, it is the natural tendency of every body to continue in its e xisting state. During takeoff, the passengers inside were initially at rest and because the aeroplane were at rest. When it started to move, the state is changed. The seats also will move along with the aeroplane since it is attached to the aeroplane. But, our body will resist the change of state and it will try to continue in its state of rest. So, the body will move backward initially during the take off. Conclusion Newton’s first law is also known as the law of inertia. Inertia depends on mass. If mass increases, inertia also will increase.
