Terminal velocity
Terminal velocity
Constant speed when gravity = air resistance
Does object accelerate at terminal velocity?
Does object accelerate at terminal velocity?
No, it stops accelerating
Resultant force at terminal velocity
Resultant force at terminal velocity
Zero
Effect of larger surface area
Effect of larger surface area
Greater air resistance, lower terminal velocity
3 factors affecting terminal velocity
3 factors affecting terminal velocity
Mass, shape, and fluid
Acceleration of free fall under gravity
Acceleration of free fall under gravity
m/s²
What happens as drag forces increase?
What happens as drag forces increase?
Acceleration decreases until terminal velocity reached
Steep gradient on velocity-time graph
Steep gradient on velocity-time graph
High initial acceleration
Why does gradient flatten on v-t graph?
Why does gradient flatten on v-t graph?
Drag increases, reducing acceleration to zero
When skydiver reaches terminal velocity
When skydiver reaches terminal velocity
When air resistance equals gravity force
