* Terminal velocity depends on several factors:
* Object's shape and size: A streamlined object will reach a higher terminal velocity than a wider one.
* Object's mass: Heavier objects generally have higher terminal velocities.
* Density of the fluid (air or water): Terminal velocity is lower in denser fluids.
* The fluid's viscosity: A more viscous fluid will create more drag, lowering terminal velocity.
Think of it like this:
* Imagine a feather and a bowling ball falling. The bowling ball will hit the ground much faster because it has more mass and less surface area, resulting in higher terminal velocity.
Key takeaways:
* Terminal velocity is the constant speed that a freely falling object eventually reaches when the force of gravity pulling it down is balanced by the force of air resistance pushing it up.
* It's not a fixed number; it varies based on the factors listed above.
Examples:
* A human skydiver might reach a terminal velocity of about 120 mph (193 km/h) in a belly-to-earth position.
* A smaller object, like a raindrop, might only reach a terminal velocity of a few miles per hour.
