The measure of force of gas particles against a surface is known as pressure (P). In SI units the force of gas pressure is in ATM(s) and Pascal's.
The measure of the force with which air molecules push on a surface is air pressure. An instrument that is used to measure air pressure is a barometer.
good question...
The measure of the force due to air pressing on a surface is called the force.If you divide that by the area of the surface, then you have the pressure.

Sand is made up of fine particles so there are spaces between the particles so as run your feet push on the ground, however unlike on normal ground some of force you exert to push yourself forward is used to compress the sand particles closer together so you require more force to compensate to move forward as the reaction force is lower in proportion.

A push or a pull is a force
The electromagnetic force can push things apart. This force exists between charged particles and can cause similar charges to repel each other. Additionally, the force of gravity can also push things apart on a cosmological scale due to the expansion of the universe.
Air pressure is the measure of the force with which air molecules push on a surface.
mass cannot be called a force.* Mass is the amount (quantity) of matter within a body. Force is the push- or pull-energy exerted on mass.
Energy can be transferred to material things by pushing or pulling AND moving it through a distance. The push or pull is a force, and the amount of energy is the magnitude of the force multiplied by the distance through which it acts. No matter how hard you push or pull, if your force doesn't move through any distance, then no energy is transferred to the thing you're pushing or pulling.
What is normally used here is not a force, but a force per unit area; this is called pressure. The SI unit for pressure is the pascal.
