IF A MAN STANDS ON A BENCH
AND THE WEIGHT OF THE MAN
PUSHES DOWN ON THE BENCH
WITH A FORCE OF 750 N. THE
BENCH PUSHES BACK UP WITH A
FORCE OF 750N . THE FORCES
ARE BALANCED
FORCES
ARE ACTING
ON
EVERYTHING
ALL THE
TIME
IF AN OBJECT IS MOVING AND
THE FORCES ARE BALANCED,
THEN IT WILL CONTIUE TO
MOVE AT THE SAME SPEED IN
THE SAME DIRECTION UNTIL
SOMETHING HAPPENS TO MAKE
THE FORCES UNBALANCED
A BOAT FLOATS BECAUSE THE
WEIGHT OF THE BOAT ACTING
DOWNWARDS IS EXACTLY
BALANCED BY THE UPTHRUST
FROM THE WATER ACTING
UPWARDS. THE FORCES
BALANCED
UNBALANCED FORCES MAKE
THINGS CHANGE; SPEED,
SHAPE AND DIRECTION
