Pressure

• What is the definition of pressure?

  Force per unit of area
• How is pressure quantified?

  Using the formula: pressure = force/area
• What creates pressure in fluids?

  Collisions of particles with their surroundings
• What do we call the pressure generated by liquids and gases?

  Fluid pressure
• How does a gas create pressure in a container?

  Gas particles collide with the container walls
• How do water particles create pressure in a beaker?

  By colliding with the glass walls and air
• What is the significance of using perpendicular force in pressure calculations?

  Only perpendicular force contributes to pressure
• How does the angle of collision affect pressure generation?

  Only perpendicular collisions generate full pressure
• How do you calculate the perpendicular force from pressure and area?

  Multiply pressure by area
• What is the relationship between pressure, force, and area?

  • Pressure = Force / Area
  • Measured in pascals
  • Higher force or smaller area increases pressure
• What are the differences in pressure generation between solids and fluids?

  • Solids: Pressure from direct force application
  • Fluids: Pressure from particle collisions with surroundings
  • Fluid pressure acts in all directions
