Terminal velocity
Terminal velocity
Constant speed when gravity force = air resistance force
Acceleration at terminal velocity
Acceleration at terminal velocity
Zero - object stops accelerating
Resultant force at terminal velocity
Resultant force at terminal velocity
Zero - forces are balanced
Effect of larger surface area on terminal velocity
Effect of larger surface area on terminal velocity
Increases air resistance experienced
Effect of streamlined shapes on terminal velocity
Effect of streamlined shapes on terminal velocity
Affects air resistance and terminal velocity value
Three factors affecting terminal velocity
Three factors affecting terminal velocity
Mass, shape, and fluid (air or water)
Initial acceleration when falling in a fluid
Initial acceleration when falling in a fluid
m/s under gravity
What acts on falling objects after initial fall
What acts on falling objects after initial fall
Drag forces
Velocity-time graph gradient at start of fall
Velocity-time graph gradient at start of fall
Steep gradient - high acceleration initially
Velocity-time graph at terminal velocity
Velocity-time graph at terminal velocity
Flat gradient - no acceleration
