BALANCED AND UNBALANCED FORCES

BALANCED AND UNBALANCED FORCES

1. THE UNIT FOR ALL FORCES IS THE NEWTON

2. 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

3. FORCES ARE ACTING ON EVERYTHING ALL THE TIME

4. 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

5. 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

6. UNBALANCED FORCES MAKE THINGS CHANGE; SPEED, SHAPE AND DIRECTION
