What is pressure

Cards (14)

  • What is the definition of pressure?
    Pressure is defined as the force per unit of area.
  • How can pressure be quantified?
    Pressure can be quantified using the formula: pressure = force / area.
  • If you apply a force of 800 newtons to a nail head with an area of 0.0001 meters squared, what is the resulting pressure?
    The resulting pressure is 8 million pascals or 8,000 kilopascals.
  • What generates pressure in fluids like liquids and gases?
    Pressure in fluids is generated by particles constantly colliding with their surroundings.
  • How does gas pressure occur in a container?
    Gas pressure occurs due to collisions of gas particles with the walls of the container.
  • How does liquid pressure manifest in a beaker of water?
    Liquid pressure manifests as water particles collide with the glass walls and air at the surface.
  • What do we refer to pressure generated by gases and liquids as?
    We refer to it as fluid pressure.
  • What component of force is used to calculate pressure?
    We use the perpendicular component of the force to calculate pressure.
  • How does the angle of impact affect the pressure generated by a particle?
    A particle striking perpendicularly uses the entire force to generate pressure, while an angled impact uses only a smaller component of the force.
  • What is the formula to calculate the force exerted on an area given the pressure?
    The formula is force = pressure × area.
  • How do you convert kilopascals to pascals?
    You multiply kilopascals by 1000 to convert to pascals.
  • If the pressure is 60 kilopascals and the area is 0.5 meters squared, what is the force exerted?
    The force exerted is 30,000 newtons or 30 kilonewtons.
  • What is the process to calculate the force exerted given pressure and area?
    1. Convert pressure from kilopascals to pascals (multiply by 1000).
    2. Use the formula: force = pressure × area.
    3. Calculate the force using the given values.
