The magnitude of the friction force depends directly on the surface of the bodies involved in contact, as the rougher the surface, the greater the magnitude of this force. In addition, there are also some external factors that can influence the magnitude of this force such as temperature, pressure, and humidity present in the environment where the bodies are located. Which of the alternatives below incorrectly presents the external influences on the magnitude of the friction force?

Mass directly influences the magnitude of the friction force because the higher the masses, the greater the magnitudes of these forces.

Temperature directly influences the magnitude of the friction force because the higher the temperatures, the greater the magnitudes of these forces

Pressure directly influences the magnitude of the friction force because the higher the pressures, the greater the magnitudes of these forces

Humidity directly influences the magnitude of the friction force because the higher the humidities, the greater the magnitudes of these forces

Velocity directly influences the magnitude of the friction force because the higher the velocities, the greater the magnitudes of these forces
