Pressure Between Solids

What is the unit of measurement for pressure?

• Pascal (Pa)
• Watt (W)
• Joule (J)

• Newton (N)

Which unit is equivalent to 1 Pa of pressure?

• 1 N/m

• 1 kg/m²

• 1 N/m³

• 1 N/m²

What is the equation used to calculate pressure?

• Pressure = Force / Area
• Pressure = Area / Force
• Pressure = Mass / Volume
• Pressure = Force + Area

Which statement best describes the definition of pressure?

• Pressure is the force applied per unit area.
• Pressure is the weight applied to an object's area.

• Pressure is the product of force and area.

• Pressure is the area per unit of force.

Consider two cubes, one with a smaller volume and the other with a larger volume, both having the same mass. Which cube will exert more pressure on the floor?

• The smaller cube

• The larger cube

• They will exert the same pressure.

• More information is needed to determine the answer.

Army tank tracks are useful for travelling through the mud because..

• they decrease the force the vehicle exerts on the ground
• they increase the force the vehicle exerts on the ground
• they decrease the pressure the vehicle exerts on the ground
• they increase the pressure the vehicle exerts on the ground

What happens to the pressure exerted by an object if its area of contact with the ground is doubled while keeping the force constant?

• The pressure doubles

• The pressure halves

• The pressure remains the same

• The pressure quadruples

• A person lying flat on their back

• A person standing on one foot

• A person kneeling on both knees

• A person sitting cross-legged
