Terminal velocity
Terminal velocity
Constant speed when falling object stops accelerating
Condition for terminal velocity
Condition for terminal velocity
When air resistance equals weight (forces balanced)
Free fall
Free fall
When gravity pulls object down, making it speed up
Acceleration due to gravity near Earth
Acceleration due to gravity near Earth
Stage 1 of falling: forces
Stage 1 of falling: forces
Weight down, little air resistance, quick acceleration
Stage 2 of falling: air resistance
Stage 2 of falling: air resistance
Gets stronger, weight > air resistance, slower acceleration
Stage 3 of falling: terminal velocity
Stage 3 of falling: terminal velocity
Air resistance = weight, balanced forces, constant speed
Resultant force at terminal velocity
Resultant force at terminal velocity
Zero (forces balanced)
Effect of larger surface area on terminal velocity
Effect of larger surface area on terminal velocity
More air resistance, lower terminal velocity
Effect of heavier objects on terminal velocity
Effect of heavier objects on terminal velocity
Higher terminal velocity
Terminal velocity in thick liquid vs air
Terminal velocity in thick liquid vs air
Lower in thick liquid than in air
When air resistance equals weight during fall
When air resistance equals weight during fall
Object falls at constant speed (terminal velocity)
Acceleration at terminal velocity
Acceleration at terminal velocity
Zero (object stops accelerating)
Parachute opens during fall: effect
Parachute opens during fall: effect
Air resistance > weight, object slows down
