What is the opposite of an inverse relationship?

The opposite of an inverse relationship is a direct relationship. Two or more physical quantities may have an inverse relationship or a direct relationship. Temperature and pressure have a direct relationship, whereas volume and pressure have an inverse relationship.

In an inverse relationship, when one quantity increases the other decreases. For example, when pressure is increased, the volume decreases.

In a direct relationship, both physical quantities may increase or decrease simultaneously. For example, when pressure increases, temperature also increases. When pressure falls, the temperature falls too. The area of a circle is in direct relationship with the radius of the circle.
