CONCEPT OF INERTIA: GALILEI VS NEWTON
CONCEPT OF
INERTIA
INERTIA is the tendency of
any matter to resist change
in the velocity.
INERTIA is the tendency of
any object to resist change
in its state of motion.
GALILEO’S
CONCEPT OF
INERTIA
NEWTON’S LAW
OF INERTIA
Galileo’s idea is the
FOUNDATION of
Newton’s Law of
Inertia.
FORCE is not
necessary to
sustain MOTION.
A body in motion will
remain in motion unless
a FORCE (FRICTION)
will cause it to rest.
Any object at rest will
remain at rest and object
in motion will remain in
motion unless acted by an
UNBALANCED FORCE.
UNBALANCED FORCED
OR NET FORCED
is the total force applied to
any object.
INERTIA depends on
the mass of an object.
3 TYPES OF INERTIA
1. At rest
2. Motion
3. Direction

STUDY MATERIAL IN PHYSICS: CONCEPT OF INERTIA: GALILEI VS NEWTON CONCEPT OF INERTIA Galileo Galilei Isaac Newton (1564 – 1642) (1643 – 1727) INERTIA is the tendency of INERTIA is the tendency of any matter to resist change in the velocity. any object to resist change in its state of motion. GALILEO’S CONCEPT OF INERTIA NEWTON’S LAW OF INERTIA Galileo’s idea is the FOUNDATION of Newton’s Law of Inertia. A body in motion will remain in motion unless a FORCE (FRICTION) will cause it to rest. GALILEO’S MARBLE AND INCLINED EXPERIMENT “FORCE is not necessary to sustain MOTION.” Any object at rest will remain at rest and object in motion will remain in motion unless acted by an UNBALANCED FORCE. UNBALANCED FORCED OR NET FORCED is the total force applied to any object. - He concluded that any object will continue to move FOREVER without slowing down. INERTIA depends on the mass of an object. - It will only stop if a force will stop it. 3 TYPES OF INERTIA 1. At rest 2. Motion 3. Direction Name: Description: ...
