Q4 G12 PERIODICAL EXAM

He said that: "The vertical motion of an object depends on the kind of element that makes up the object which can be earth, water, air or fire."

• Aristotle

• Galileo

• Socrates

• Copernicus

WHOSE LAW OF MOTION IS THIS?

All objects remain at rest or in uniform motion along a straight line unless acted by an external force.

Object’s velocity changes when subjected to an external force. Force is equal to change in momentum per time interval.

An action force has always an equal and opposite reaction force.

• Isaac Newton

• east to west

• west to east

• north to south

• south to north

WHOSE LAW OF MOTION IS THIS?

Key observations regarding an object’s motion :

(1)development of the concept of velocity using inclined planes

(2)development of the idea of force that causes the motion of an object

(3)being at rest is the natural state of an object

(4)inertia is the resistance of an object to changes in its motion

• Galileo Galilei

• Galileo Galileo

• Isaac Newton

• Fig Newton

1.All matter is composed of atoms.

2.All atoms of an element are entirely identical.

3.Atoms are indestructible and unchangeable.

4.Elements react to form compounds in defined ratios.
WHAT IS THIS THEORY CALLED?

• The Hybrid Atomic Theory

• The Classic Atomic Theory

• The Atomic Theory

• The Modern Atomic Theory
