Understanding Pressure and Friction

What do we use to measure pressure?

• Speedometer

• Thermometer

• Manometer or Barometer

• Voltmeter

What happens to fluids when they move?

• Fluids become solid when they move.

• Fluids flow and can change pressure and viscosity when they move.

• Fluids do not change their properties regardless of movement.

• Fluids always increase in temperature when they move.

Can you name a principle that helps us understand how air moves?

• Archimedes' principle

• Newton's law of motion

• Pascal's law

• Bernoulli's principle

How do we find out how much water flows in a pipe?

• The flow rate of water in a pipe can be calculated using the formula: Flow Rate = Cross-sectional Area x Flow Velocity.

• The water flow can be measured by the pipe's length.

• Water flow is determined by the temperature of the water.

• The pressure of the water is the only factor affecting flow.

What is one type of friction we see in liquids?

• Static friction

• Kinetic friction

• Rolling friction

• Viscous friction

Where do we see pressure drop in our daily lives?

• Car tires, water pipes, vacuum cleaners

• Refrigerators

• Air conditioning units

• Coffee makers

What tool helps us see how much pressure is in a tire?

• Tire tread depth gauge

• Tire pressure gauge

• Air compressor

• Tire inflator

What is it called when things slide against each other?

• Friction

• Inertia

• Momentum

• Gravity

How does friction affect how fast a boat moves?

• Friction slows down a boat by creating resistance against its movement.

• Friction increases the boat's buoyancy, allowing it to glide more easily.

• Friction helps a boat move faster by reducing drag.

• Friction has no effect on a boat's speed.

Why is it important to know about pressure in water pipes?

• To calculate the length of the pipes

• To measure the temperature of the water

• It is important to know about pressure in water pipes to ensure efficient water flow, prevent leaks, and avoid pipe bursts.

• To determine the color of the water
