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.
A spring scale is typically used to measure the force of push or pull exerted on an object. The stretch or compression of the spring in the scale can be used to determine the magnitude of the force acting on the object.

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.
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.
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.
Matter can move without an external force if it possesses kinetic energy. However, in order to change its speed or direction, a force is typically required to push or pull on it.
Force can be either a push or a pull. When you push a door open or pull a rope, you are applying a force in that direction.
Air pressure is the measure of the force with which air molecules push on a surface.
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.
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.
