What is Pressure ?

• What concept is covered in today's video?

  Pressure
• How is pressure defined?

  As the force per unit of area
• What is the formula for calculating pressure?

  Pressure = Force / Area
• What units is pressure measured in?

  Pascals
• If a force of 800 newtons is applied to an area of 0.0001 m², what is the pressure generated?

  8 million pascals
• What creates pressure in fluids?

  Collisions of particles with surroundings
• How does gas pressure occur in a container?

  From gas particles colliding with the walls
• What happens to pressure in a beaker of water?

  Water particles apply forces in all directions
• What do we call pressure generated by fluids?

  Fluid pressure
• What type of force is used to calculate pressure?

  Perpendicular force
• How does the angle of impact affect pressure generation?

  Perpendicular impact maximizes pressure generation
• What is the perpendicular force exerted on a 0.5 m² area by a pressure of 60 kilopascals?

  30,000 newtons
• How do you convert kilopascals to pascals?

  Multiply by 1000
• What is the process to calculate force from pressure and area?

  • Use the formula: Force = Pressure × Area
  • Convert pressure to pascals if necessary
  • Multiply by the area to find force
• What are the key differences between perpendicular and angled impacts on pressure?

  • Perpendicular impacts use full force for pressure
  • Angled impacts use only a component of the force
  • This affects the overall pressure generated
