how the velocity vector drawn with red color can be broken into x-y-z components ?Chestermiller said:
how you came to know that?Chestermiller said:
You can always resolve a vector into components.gracy said:
You can see in the figure that the wall that it bounces off is parallel to the y-z plane.
i know how to resolve vectors but only in 2 dimensions.Chestermiller said:
Well, it can be done in 3 dimensions too.gracy said:
can all vectors be resolved in 3 dimensions?Chestermiller said:
Yes. In 3D space, all vectors can be resolved into combinations of 3 linearly independent components.gracy said:
but only vectors which are in 3d ,for example this kind of vector (in the image below) can only be resolved in 2d i.e only with two perpendicular component.right?Chestermiller said:
All that means is that the component out of the paper is zero.gracy said:but only vectors which are in 3d ,for example this kind of vector (in the image below) can only be resolved in 2d i.e only with two perpendicular component.right?
ok if any vector is coming out of page ,what it's x component would be?i can only imagine it in y z plane.Chestermiller said:
If the vector is through the origin, then you drop a normal from its tip to each of the three coordinate axes to get its x, y, and z components.gracy said:
From Tip of vector which has to be resolved?Chestermiller said:
Yes.gracy said:
The pressure of an ideal gas is defined as the force exerted by the gas on the walls of its container per unit area. It is caused by the collisions of gas molecules with the container walls.
According to the ideal gas law, the pressure of an ideal gas is directly proportional to its temperature and inversely proportional to its volume. This means that as temperature increases, pressure increases, and as volume increases, pressure decreases.
The unit of measurement for pressure of an ideal gas is typically expressed in pascals (Pa) or kilopascals (kPa). In some cases, other units such as atmospheres (atm) or millimeters of mercury (mmHg) may also be used.
The pressure of an ideal gas is directly proportional to the number of gas molecules present in a given volume. This means that as the number of gas molecules increases, the pressure also increases, and vice versa.
No, the pressure of an ideal gas cannot be negative. Since pressure is defined as a force per unit area, it must always have a positive value. Negative pressure would imply that the gas is pulling rather than pushing on its container, which is not possible in an ideal gas.
