The video tutorial explains what a clinometer is and how it is used to measure the incline or slope of an object. It provides an example of measuring the height of tall structures like the Burj Khalifa using the angle of elevation and trigonometry. The tutorial also includes a detailed guide on constructing a clinometer using simple materials such as a protractor, straw, and string.

What is the primary function of a clinometer?

• To measure weight

• To measure angles of elevation and depression

• To measure speed

• To measure temperature

Why might you use a clinometer to measure the height of a tall building?

• Because it is easier to use than a ladder

• Because it is a traditional method

• Because it is more accurate than a measuring tape

• Because it allows you to calculate height using angles and trigonometry

Which of the following is NOT a material needed to construct a clinometer?

• Protractor

• String

• Thermometer

• Straw

What is the purpose of attaching a heavy weight to the string in a clinometer?

• To decorate the clinometer

• To balance the clinometer

• To ensure the string remains taut for accurate angle measurement

• To make the clinometer heavier

Where should the straw be placed on the protractor during the construction of a clinometer?

• On the 0-degree line

• On the 180-degree line

• On the 90-degree line

• On the 45-degree line
