Pressure is a scalar quantity. It is defined as the force per unit area and only has magnitude, not direction.
A vector quantity.
Air pressure in a tire is a scalar quantity because it has magnitude but no specific direction associated with it.
No, a scalar quantity cannot be added to a vector quantity directly. They belong to different types of quantities - scalars have only magnitude while vectors have both magnitude and direction. To add a scalar to a vector, you would need to convert the scalar to a vector by giving it a direction and then perform vector addition.
No, a vector quantity and a scalar quantity are different. A vector has both magnitude and direction, while a scalar has only magnitude. Velocity and force are examples of vector quantities, while speed and temperature are examples of scalar quantities.
A scalar quantity has only magnitude, while a vector quantity has both magnitude and direction. Scalars are represented by a single numerical value, while vectors are represented by both magnitude and direction, often using arrows.
