Why do the rain drops fall with constant speed during the later stages of their journey?
Correct answer: A. The air resistence just balances the force of gravity
- A. The air resistence just balances the force of gravity
- B. The force of gravity ois constant for all drops
- C. All drops fall from the same height
- D. The drops are small so force of gravity is negligible for them
Explanation
Terminal velocity, the steady speed achieved by an object freely falling through a gas or liquidLet's go into the imagination A raindrop falling through a ( air) ,When it just started falling, there was air resistance that was acting on itAs it continues its journey, air resistance increases until it becomes equal to the force of gravity Then the drop will have a constant speed and that speed is called terminal speed.Parachutes work on the same basis

About Terminal Velocity
Terminal velocity is the constant speed reached when gravitational force is balanced by fluid resistance. The topic covers drag, buoyant force, the conditions for zero acceleration, and how viscosity, object size, shape and density affect the limiting speed, with a distinction between free fall before and after terminal velocity.
