Terminal Velocity and Air Resistance | GCSE Physics
Objects falling through a fluid eventually reach a constant speed called terminal velocity.
What is the sum of forces on an object at terminal velocity?
What is Terminal Velocity and Air Resistance | GCSE Physics?
"The constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration."
What is the resultant force on an object if a 10N force acts right and a 4N force acts left?
Which of these is the correct vector equivalent of 'Distance'?
An object moves at a constant velocity. What is the resultant force?
What is the unit of the spring constant (k)?
Air Resistance
Initial fall: Acceleration is high (Weight > Drag).
As speed increases, air resistance (drag) increases.
Eventually, Drag = Weight.
Resultant force becomes zero and acceleration stops.
Graph Tip: A velocity-time graph for terminal velocity starts steep and levels off into a horizontal line.
