No, raindrops do not reach terminal velocity because they are too small and have a low enough mass that air resistance slows them down before they can reach their maximum falling speed. Terminal velocity is typically reached by larger objects like skydivers or hailstones.
No, terminal velocity does not depend on the mass of the object. Terminal velocity is the maximum speed an object can reach when the force of gravity is balanced by the force of drag. This means that all objects, regardless of their mass, will eventually reach the same terminal velocity in a given medium.
No, an acorn is too small and light to reach its terminal velocity when falling from a tree. Terminal velocity is the maximum constant speed that an object reaches when the drag force equals the force of gravity, and the small size and weight of an acorn mean that it doesn't experience enough air resistance to reach this terminal velocity.
Skydivers reach terminal velocity because as they fall, the force of gravity pulling them downward is balanced by air resistance pushing upward. At terminal velocity, these forces are equal, so the skydiver stops accelerating and falls at a constant speed.
Yes, terminal velocity is the highest velocity that a falling object will reach when the force of air resistance equals the force of gravity acting on the object, causing it to no longer accelerate. At terminal velocity, the object falls at a constant speed without further acceleration.
An egg would typically reach terminal velocity in about 12 to 15 seconds when dropped from a significant height. Terminal velocity is the point at which the force of gravity on the egg is equal to the force of air resistance, causing the egg to no longer accelerate.
