Terminal velocity
Terminal velocity
Constant speed when air resistance equals gravity
Resultant force at terminal velocity
Resultant force at terminal velocity
Zero
Acceleration at terminal velocity
Acceleration at terminal velocity
Zero - object stops accelerating
Effect of larger surface area on terminal velocity
Effect of larger surface area on terminal velocity
Increases air resistance, lowers terminal velocity
