So I understand that when an electric field is produced in a conductor of length L, the net electric field in the conductor will be 0 because the rearrangement of electrons in the conductor results in the production of its own electric field which cancels out the one produced initially...
@A.T. It's not hard to imagine. But WHY(hope you see those capitalized letters) do they stop eventually? @Nidum I know seat belts are there to stop eventually. But without seatbelts, will the occupant still stop? Or will he keep on going until he bangs into the windowscreen
Normal reaction force which originally is the normal force of the wall on the car. How does the occupant experience this force since he eventually comes to a stop?
During a collision between a truck and a wall, an occupant of the truck is thrown forward because of inertia; he continues moving forward. Why does the occupant stop eventually? What is the resultant force that opposes his forward motion? Is this force the equal and opposite normal reaction...
it's in the question: I think that "air resistance could decrease as the upward velocity of the ball decreases or it could increase and then remain constant even when the upward velocity of the ball decreases" Air resistance could decrease because it is strictly dependent on air resistance...
If air resistance increases with velocity, then if a ball is thrown upwards, does air resistance decrease as the upward velocity of the ball decreases or does it only increase and remains constant when the upward velocity of the ball decreases?
