Grade 9 STS PASCAL'S LAW

If a box with an area of 10m sq has a a 120n force exerted on it, what is the pressure on the box?

• 5pa

• 12pa

• 25pa

• 2pa

What is the equation for pressure?

• Pressure = Force / Surface area
• Pressure = Force x Surface area
• Pressure = Force + Surface area
• I have a 6 foot squirrel named Antney

What does pressure measure?

• Strength
• Force exerted on a given area of surface

When you increase your depth under water, the water pressure on your body

• increases
• decreases
• stays the same

why you feel lighter in the swimming pool

• because of the buoyant force

• because of gravity

• because water is light

• because gravity decreases

The unit for pressure

• Pascal

• Newton

• Gram

• Miles

When VELOCITY increases...

• pressure decreases

• pressure increases

• pressure stays the same

• pressure increases then decreases
