When driving a car around a corner, why do we feel as if we are thrown away from the corner?
Correct answer: B. Your inertia wants you to keep moving in a straight line.
- A. There is a force acting on you away from the center of the turn called centrifugal force which gives this feeling.
- B. Your inertia wants you to keep moving in a straight line.
- C. Your body offers a reaction force to the centripetal force of the turn away from the center.
- D. The turn causes a pressure difference on either side of the car which causes you to move towards the region of low pressure which is away from the center of the curve.
Explanation
When you drive around a corner, your body wants to continue in a straight line due to inertia, as described by Newton's first law of motion. This creates the sensation of being 'thrown' outward. However, as the car turns, the door or seat applies a centripetal force towards the center of the curve, altering your path to match the car's. This force is what actually keeps you moving in a curved path.Option A is incorrect because centrifugal force is a perceived effect, not an actual force. Option C misunderstands the nature of action-reaction pairs, and option D incorrectly attributes the sensation to pressure differences, which are not the cause in this scenario.

About Scientific Reasoning
Scientific reasoning evaluates hypotheses through observations, variables, controls, measurements and experimental results. Questions involve identifying independent and dependent variables, recognising a fair test, interpreting tables or graphs, distinguishing evidence from opinion, and deciding whether data supports, rejects or leaves a hypothesis unresolved.
