Is it possible to have a negative area?

Question

Is there any physics assumption or theory that allows a negative area or volume?

Answer 1

no

Answer 2

A very simple answer -- NO!

Answer 3

In physics area is a vector quantity which is explained as cross product of the two vectors that make it sides. the direction of area is perpendicular to the plane of the area. Reversing the order of vectors in cross product reverse the direction leaving the magnitude unchanged. so on that basis area can be negative. but that does not mean that its magnitude be negative. The whole game is about direction.

Physically volume is a scalar quantity. It is always positive. However if you find the volume in a problem and comes out negative, that then means that the change in volume is such that the initial volume of the system under consideration was greater than the final volume, that is, the volume has shriked.

Answer 4

no never. How can you have a negative length

Answer 5

Maybe in a hyper dimensional sense that included time as a dimension, but not in our universe. Time is equivalent to an imaginary distance in Relativity. If a universe has two time dimensions, a particle could circumnavigate an area with negative area in space-time.

Answer 6

nope because once u get an equation that says it is negative that just means it started a new positive area on the other side

its almost like saying I'm negative 20 years old

Answer 7

no. These are physical quantities, and can't be negative.
