What do we call the the amount of force exerted on a certain area?

fluid

pressure

buoyant

What is the formula for pressure?

P=A/F

P=FA

P=F/A

To calculate pressure you need to know ...

Force & Volume

Density & Volume

Power & Area

Force & Area

The pressure resulting from a force of 50 N exerted over an area of 5 m² is

10 N

0.1 N

10 N/m²

0.1 Pa

When force increases...

pressure increases

pressure decreases

pressure stays the same

pressure increases then decreases

When area increases...

pressure increases

pressure decreases

pressure stays the same

pressure increases then decreases

Pressure can be measured in Pascals (Pa) or Newtons per square metre.

1 Pa = 1N/m²

True

False

Water pressure increases as depth increases.

True

False

Archimedes' Principle states that...

The buoyant force acting on an object equals the volume of the fluid displaced by the object.

The buoyant force acting on an object equals the weight (force of gravity) of the fluid displaced by the object.

The buoyant force acting on an object will always be equal.

Look at the pressure triangle. How do we calculate the area?

f ÷ a

f x p

p x f

f ÷ p

11.

Look at the pressure triangle. How do we calculate the force?

f ÷ a

f x p

p x a

f ÷ p

12.

What is the formula for density?

density = mass x volume

density = mass / volume

density = mass + volume

density = mass - volume

Jill has a gel pen. The gel pen has a mass of 8g and a volume of 2cm³. What is the density of the pen?

4 g/cm³

16 g/cm³

.25 g/cm³

64 g/cm³

17.

If the mass of an unknown substance is 5.3 grams and the volume is 2 cm³. What would be its density? (round)

2.7 g/cm³

2.5 g/cm³

2.4 g/cm³

2.2 g/cm³

13.3 g

13.3 cm³

.075 g

1695 cm³

19.

The density of this material is 2 g/cm³.
There are 24 cm³ Find the total mass.

12 grams

48 grams

12 g/cm³

48 g/cm³
