The answer depends on what kind of pressure. If you mean the pressure exerted by gasses on the walls of a container (a balloon, for example), pressure is created by the motion of the molecules of gas. Temperature and density of the molecules are factors. Higher density results in higher pressure. Higher temperature creates more molecular motion, thereby creating higher pressure.
Air pressure is caused by the weight of the air above pushing down on the air below. As altitude increases, there is less air above, resulting in lower air pressure. Temperature and humidity can also affect air pressure.
In layman terms, warm air rises and cold air sinks (experience that in a two-story building). Lighter objects float to the top. Therefore, warm air has a lower density than cold air. ===============================
By definition, friction is opposite of the direction of motion.
Dynamic pressure is the force exerted by a fluid in motion, such as air or water, on an object moving through it. It is defined as 0.5 times the fluid density times the flow velocity squared. Dynamic pressure is an important parameter in aerodynamics and fluid dynamics for predicting the forces acting on a moving object.

An acceleration data logger measures and records the activity and motion. They are used to find the activity of temperature, humidity, and pressure.

The motion of atoms or molecules in a substance is related to its temperature, with higher temperatures leading to increased motion. This motion affects the state of matter (solid, liquid, gas) that the substance is in, as well as its properties such as density and viscosity. In gases, the motion of atoms or molecules creates pressure.
They both spin on an axis.

In fluid dynamics, static pressure is the pressure exerted by a fluid when it is not in motion, while total pressure includes both the static pressure and the pressure caused by the fluid's motion.
It is in most cases opposite to the direction of motion.
By definition, friction is opposite of the direction of motion.
Yes, atmospheric pressure is determined by the combined effect of temperature, air density, and the concentration of water vapor present in the air. These factors influence the overall molecular motion and interactions within the atmosphere, directly impacting the pressure exerted by the air at a given location.

When the motion of particles slows down, the particles will have less kinetic energy. This could result in a decrease in temperature or a phase change, depending on the substance. The particles may also start to move closer together, leading to changes in density or pressure.
