The pressure on the windows was generated by air pushing on the windows, which is the average the air molecules are applying over the surface area of the glass. velocity acceleration force density

Force

Explanation:

The pressure is defined as the ratio between the force applied on a surface divided by the area of the surface:

where F is the force applied and A is the area of the surface.

Therefore, in this specific case, the pressure on the window is generated by the air pushing on the window, and that pressure is given by the average force of the air molecules divided by the surface area of the glass.

Pressure is NOT a Velocity, an Acceleration, a Force, or a Density.

Pressure is the average force per unit area the air molecules are applying over the surface area of the glass.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
