Question 1

Why does an object reach terminal velocity?

Answer 1

When an object is falling, a downwards force is acting on the object due to gravitational forces

This causes it to accelerate

As the object accelerates, the air resistance increases

Eventually the force due to gravity is balanced by the air resistance

So the object is now falling at a constant speed

This constant speed is the terminal velocity of this object
