Understanding Terminal Velocity
* Gravity: When an object falls, gravity pulls it downwards.
* Air Resistance: As an object falls through the air, it encounters resistance from the air molecules. This resistance increases as the object's speed increases.
* Terminal Velocity: The point where the force of gravity pulling the object down is exactly balanced by the force of air resistance pushing it up. At terminal velocity, the object stops accelerating and falls at a constant speed.
Why the Heavier Ball Experiences Greater Air Resistance at Terminal Velocity
1. Force of Gravity: The heavier ball experiences a stronger gravitational force. This means it needs a greater force of air resistance to counterbalance it.
2. Achieving Equilibrium: To reach terminal velocity, the heavier ball needs to build up a larger air resistance force to match the stronger gravitational pull.
3. Larger Air Resistance Force: The heavier ball will reach a higher terminal velocity than the lighter ball. This is because a higher speed is required to create enough air resistance to equal the heavier ball's gravitational force. Since air resistance increases with speed, the heavier ball will experience greater air resistance at its terminal velocity.
In Summary:
While both balls have the same size and shape, the heavier ball will experience greater air resistance at its terminal velocity because it needs to achieve a higher terminal velocity to balance the stronger force of gravity acting on it.
