Help mr with physics problems?

A frantic weather reporter is reporting on a live tornado. The reporter exclaims, “Wood, metal, and all kinds of debris are being thrown directly outward from the edge of the funnel.” In light of your understanding of circular motion, comment on the accuracy of the reporter’s statement.



The tire on your car is almost flat and, therefore, a large portion of the tire’s surface is in contact with the street. When you pump it up, less of the tire’s surface is in contact with the street. Explain why a change in tire pressure changes the amount of tire surface in contact with the street.Help mr with physics problems?
I'll give you a clue - you fill out the words:

(a) flying off tangentially, not directly outward

(b) pressure x area = downward force on road must equal weight of car on wheelHelp mr with physics problems?
it gets bigger(and rounder) the sides get lifted up as it gets rounder so only a smaller part on the bottom comes in contact with the roadHelp mr with physics problems?
outward and up



pressure in the tire keep the weight of the car for pushing it down so much forms a better circle
1st is to do with centrifugal forces

as something is spun, it is thrown outwards from its axis



2nd as the tyre inflates, air pressure in the tyre pushes outwards in all directions causing the car to rise. the increase in tyre pressure eventually counteracts the weight of the car, restoring the tyre to its natural shape, which reduces the area of tyre in contact with the road
