What has to happen for an object to fall through a fluid? (1)
There are 2 forces acting: its weight due to gravity and the drag force.
What has to happen for an object to fall through a fluid? (2)
The weight remains constant.
What has to happen for an object to fall through a fluid? (3)
The drag force is small at the beginning, but gets bigger as it speeds up.
What has to happen for an object to fall through a fluid? (4)
The resultant force will get smalle as the drag force increases.
What has to happen for an object to fall through a fluid? (5)
The acceleration will decrease as it falls.
What has to happen for an object to fall through a fluid? (6)
If it falls for a long enough time, the object will reah a final steady speed.
What’s terminal velocity?
The constant velocity a falling object reaches when the frictional force acting on it is equal to its weight.
