Answer:
Bernoulli's principle explains how objects heavier than air are able to fly
Step-by-step explanation:
Basically, Bernoulli's principle states that faster-moving air has greater air pressure than slower-moving air
When an object has greater air pressure on its top surface than its lower surface it will create lift, or lift the object up
Thus in a tornado, with extremely high winds a roof could be easily lifted up if the air pressure is greater than the force of gravity
