LAWS OF MOTION

LAWS OF MOTION

THERE ARE THREE LAWS OF MOTION:

1. NEWTON'S FIRST LAW OF MOTION GIVES RISE TO THE IDEA OF INERTIA AND MOMENTUM.

2. NEWTON'S SECOND LAW OF MOTION DERIVES A RELATIONSHIP BETWEEN THE CAUSE AND QUALITY OF MOTION.

3. NEWTON'S THIRD LAW OF MOTION GIVES RISE TO THE IDEA OF CAUSE AND EFFECT(ACTION AND REACTION).


PRINCIPLE OF INTERIA

THE TENDENCY OF A BODY TO REMAIN IN THE STATE IT IS (STATIONERY OR MOVING), IS CALLED ITS INERTIA.

MOMENTUM

WHEN YOU CATCH A BALL THAT HAS BEEN THROWN TOWARDS YOU, YOU EXPERIENCE A CERTAIN IMPACT OR INFLUENCE OF FORCE AGAINST YOR PALMS. THIS IS BECAUSE A MOVING BODY HAS MOEMENTUM. THE MAGNITUDE OF THE MOMENTUM DEPENDS UPON TWO FACTORS:

1. THE MASS OF THE OBJECT (M)
THE MORE THE MASS (i.e., THE HEAVIER THE BODY), THE GREATER IS THE MOMENTUM POSSESSED BY THE BODY.

2. THE VELOCITY WITH WHICH THE BODY IS MOVING (V)
A BODY, MOVING WITH A HIGH VELOCITY, HAS A GREATER MOMENTUM.
