Here's a breakdown:
* Free fall: This means the object is falling only under the influence of gravity.
* Air resistance: As an object falls, it encounters air resistance, a force opposing its motion. This force increases as the object's speed increases.
* Gravity: Gravity constantly pulls the object downwards.
At terminal velocity:
* The force of air resistance is equal in magnitude and opposite in direction to the force of gravity.
* The object stops accelerating and continues to fall at a constant speed.
Important Notes:
* Terminal velocity is not a fixed value. It depends on factors like the object's shape, size, mass, and the density of the air.
* Objects with larger surface areas and lower mass generally have lower terminal velocities. This is because they experience more air resistance.
* Terminal velocity is not the same as the maximum speed an object can reach. An object could potentially reach a higher speed if other forces are acting on it, such as a rocket engine.
