Lesson 6

Who is the person that classify all matter into five specific elements: earth, water, air, fire and aether?

• Aristotle

• Isaac Newton

• Eratosthenes

• Galileo Galilei

He refined the observations about inclined plane experiments and established his “Law of Inertia”

• Aristotle

• Isaac Newton

• Eratosthenes

• Galileo Galilei

Who performed a classical experiment at the Leaning Tower of Pisa to reject the idea that different object with different mass will fall at the different rate?

• Aristotle

• Isaac Newton

• Eratosthenes

• Galileo Galilei

According to Aristotle, this type of motion is responsible for horizontal movement and is always a result of a force acting on an object.

• Celestial motion

• Natural motion

• Violent motion

• Projectile motion

He believed in the idea that mass is directly proportional to motion. He predicted that objects with more mass will move faster than heavier with lesser mass.

• Aristotle

• Eratosthenes

• Galileo Galilei

• Isaac Newton

Complete the sentence: According to ancient Greek ideas about motion, earth elements _____.

• Want to stay on top of water elements.

• Want to stay down to the center of the Earth.

• Want to stay on top of fire elements.

• Want to stay down the fire element and on top of water element.

If you will be going back to the time of the Ancient Greek, which type of motion will you classify the fire coming out of a bonfire?

• Celestial motion

• Natural motion

• Violent motion

• Projectile motion

If you will be going back to the time of the Ancient Greek, which type of motion will you classify the movement of an object during a push or pull?

• Celestial motion

• Natural motion

• Violent motion

• Projectile motion

It is the property of objects to resist unbalanced forces that would make it change its orientation with the system.

• Air resistance

• Friction

• Gravity

• Inertia

What do we call an object that moves as a result of two independent forces, one of which is its horizontal motion, and the other is due to gravity?

• Air resistance

• Friction

• Projectile

• Trajectory
