¢ Newton's first law of motion

+ types of Inertia

+ application of law of inertia in
everyday lives

3. ISAAC ON

Isaac Newton, an English physicist and
mathematician, first proposed three laws of
motion.

4. NEWTONS LAW OFF MOTION

e describe the
relationship between
the motion of an
object and the forces
acting on it.

5. Types of Inertia

Inertia at Rest

Inertia at Motion E

Inertia at Direction ®

6. INERGTVAVATSRIESIT

An object stays where it placed and it
will stay there until you or something
else move it.

8. INERITA AT MOTION

An object will continue at the same
speed until a force acts on it.

top of it, the index card can be quickly removed while the
penny falls straight into the glass due to inertia at. |

15. An object tied with the string and its suddenly breaks, the
loose object follows a straight path tangentto the circular
motion because of inertia at.

APPLICATION OF INERTIA IN OUR DAILY LIVE

« the design of safety
devices for vehicles, like
set belts.

« due to inertia , artificial
satellite keep moving to
circular motion

« dust coming out of dust

when beaten.
