1. FORCE AND
MOTION

2. •WHAT IS THE
RELATIONSHIP
BETWEEN FORCE
AND MOTION?

3. •ARISTOT
LE

4. •CONSIDERED THAT THE
NATURAL STATE OF A BODY IS
TO REMAIN AT REST, AND A
FORCE HAS TO ACT ON A BODY
FOR IT TO MOVE AND TO KEEP IT
MOVING.

5. GALILE
O

6. •DEVELOPED IDEAS ABOUT MOTION
CONTRARY TO THE ARISTOTELIAN
THEORY. WITH HIS THOUGHT
EXPERIMENT ON A PERFECT SPEHERE
ROLLING ON INCLINED PLANE “ FREE
FROM ALL EXTERNAL AND
ACCIDENTAL OBSTACLES.

7. •NEWTON

8. •IN HIS BOOK (PRINCIPIA), ISAAC
NEWTON WROTE HIS IDEAS ON
FORCES AND MOTION BASED ON
GALILEO’S WORK. HIS ANALYSIS
OF MOTION WAS SUMMARIZED IN
HIS THREE LAWS OF MOTION.

9. 3LAWS OF MOTION
•1.LAW OF INERTIA
•2. LAW OF ACCELERATION
•3 LAW OF NTERACTION

10. LAW OF INERTIA
•THE PROPERTY OF THE BODY
THAT TENDS TO RESIST A
CHANGE IN ITS STATE OF
MOTION.

11. NEWTON’S FIRST LAW OF
MOTION STATES THAT “AN
OBJECT AT REST WILL
REMAIN AT REST, AND AN
OBJECT IN MOTION WILL
REMAIN IN MOTION,
UNLESS THERE IS FORCE
ACTING ON IT.

12. LAW OF ACCELERATION
•WHEN A NET FORCE ACT ON A BODY, THE
BODY WILL ACCELERATE IN THE DIRECTION
OF THE FORCE.
•THE DIRECTION IS DIRECTLY
PROPORTIONAL TO THE FORCE.
•ACCELERATION IS INVERSELY
PROPORTIONAL TO THE MASS OF THE
BODY.

13. •THE GREATER THE UNBALANCE
FORCE, THE GREATER THE
ACCELERATION OF THE BODY
BEING ACTED UPON. IF A FORCE
IS APPLIED TO A BODY AT ONE
TIME AND A FORCE IS AT
ANOTHER TIME.
