I WONDER - What Is Terminal Velocity?

The video explains terminal velocity, a concept where a falling object reaches a constant speed when the force of gravity is balanced by air resistance. It illustrates this with an example of two objects of different weights falling at the same speed due to having the same terminal velocity. This principle was first demonstrated by Galileo Galilei, who dropped two spheres of different weights from the Leaning Tower of Pisa, showing they hit the ground simultaneously.

What is terminal velocity?

• The speed at which an object stops moving

• The speed at which an object starts moving

• The point where air resistance equals gravitational force on a falling object

• The initial speed of a falling object

Why do two objects of the same shape but different weights hit the ground at the same time?

• Because they have the same terminal velocity

• Because they have different air resistance

• Because they are dropped from different heights

• Because they have the same weight

Who first tested the concept of terminal velocity?

• Nikola Tesla

• Isaac Newton

• Albert Einstein

• Galileo Galilei

What did Galileo drop from the Leaning Tower of Pisa to test his theory?

• Two books

• Two spheres

• Two pieces of paper

• Two feathers

What was the outcome of Galileo's experiment?

• Neither object hit the ground

• Both objects hit the ground at the same time

• The lighter object hit the ground first

• The heavier object hit the ground first
