Weight Falling Air resistance Terminal velocity Questions

Falling Gravity can only make things accelerate when there is nothing to provide an equal opposite force. Weight Falling Air resistance Terminal velocity Questions

Air resistance When an object falls it has to push against air, this provides an upwards force on the falling object. Air resistance can be increased by – The speed an object is moving – The surface area of the object – The shape of an object Weight Falling Air resistance Terminal velocity Questions

Terminal velocity An object has reached its terminal velocity when the air resistance matches the weight of an object. So when an falling object has a resultant force of 0N it has reached its terminal velocity Weight Falling Air resistance Terminal velocity Questions

Terminal velocity Air resistance (50N) Wight (100N) Air resistance (100N) Wight (100N) The forces are not balanced so the sky diver is not at terminal velocity. The forces are balanced so the sky diver is at terminal velocity. Weight Falling Air resistance Terminal velocity Questions

1)If a person has a mass of 70Kg and has 10N/Kg of gravitational field strength acting on them, what is there weight? 2)Why dose a ball on a table not fall but if you remove the table it dose? 3)What 3 things can you do to reduce the air resistance of an object?
