Based on Newton's First Law (Inertia), match each physical scenario on the left with the correct description of its resulting motion or force balance on the right.
- An express elevator abruptly comes to a halt while descending to the ground floor.Passengers' bodies resist the deceleration and continue their downward motion, causing a sensation of being pushed into the floor.
- A moving vehicle makes a sudden, sharp turn to the left at a high speed.Unsecured objects maintain their forward straight-line path, making them appear to slide toward the right side of the interior.
- A heavy steel block sits undisturbed on a perfectly level, frictionless air table.The mass remains completely stationary because no unbalanced external forces are acting upon it to change its state.
- A skydiver falls through the atmosphere at a steady, unchanging terminal velocity.The downward gravitational force is perfectly balanced by upward air resistance, resulting in zero net force.
Cevap
The elevator scenario pairs with passengers continuing downward; the turning vehicle pairs with objects moving in a straight path (appearing to move right); the stationary block pairs with remaining stationary due to no unbalanced forces; and the skydiver pairs with balanced forces resulting in zero net force.
Each pairing correctly applies the principle of inertia to a specific physical system. Newton's First Law explains both why moving objects resist stopping or turning (the elevator and vehicle scenarios) and why objects maintain their current state when forces are balanced (the stationary block and the constant-velocity skydiver).

Anahtar Kavram
Newton's First Law dictates that an object's state of motion (either at rest or moving at a constant velocity) will not change unless an unbalanced external force acts upon it. This resistance to change is known as inertia.
