What is pressure?

Pressure is the force applied per unit area on a surface.

What is the formula for pressure?

Pressure = Force ÷ Area.

What is the unit of pressure?

Pascal (Pa).

What does 1 Pascal equal?

1 Newton per square meter (1 N/m²).

What are the units of force?

Newtons (N).

What are the units of area in pressure calculations?

Square meters (m²).

How does pressure change with increased force on a fixed area?

Pressure increases.

How does pressure change with increased area under a fixed force?

Pressure decreases.

Why does a drawing pin damage a wall while a finger doesn't?

The pin has a smaller area, so it exerts more pressure.

Why do snowshoes prevent sinking into snow?

They distribute weight over a larger area, reducing pressure.

What effect does high pressure have on a surface?

It can cause dents, marks, or structural failure.

What happens if pressure on a solid is too low?

The object may not perform its function (e.g., knife not cutting).

What are examples of high-pressure tools?

Needles, nails, knives.

What are examples of low-pressure applications?

Tires, skis, snowshoes.

Why are tank tracks more effective on soft ground than wheels?

They spread the force over a larger area.

Why are building foundations made wide?

To reduce pressure on the ground.

How can you reduce pressure from a heavy object?

Increase the contact area.

Why is standing on one foot more tiring than two?

It doubles the pressure on the ground.

What affects how far something sinks into the ground?

The pressure it applies.

What does pressure depend on?

The force applied and the area over which it acts.

What's a real-world example of pressure damaging a solid?

High heels denting a wooden floor.
