THERE ARE TWO TYPES OF FORCES.THEY ARE BALANCED AND UNBALANCED FORCE.
AN UNBALANCED FORCE IS WHEN THE NET FORCE OF AN OBJECT IS ZERO NEWTON.IT CAUSES MOTION.
A BALANCED FORCE IS WHEN THE FORCES OF AN OBJECT PRODUCE A NET FORCE OF ZERO NEWTON .IT WILL NOT CAUSE MOTION.

IF SOMEONE IS PUSHING YOU ON A SWING ,THIS IS UNBALACED FORCE.

AN EXAMPLE OF BALANCED FORCES IS SITTING ON A CHAIR.
IF THE FORCE OF THE CHAIR IS 20N AND YOU HAVE A FORCE OF 20N , YOUR FORCE IS GOING TO BE 0N.20N-20N=0N.

IF THE VEHICLES FORCE IS 50N AND THE GROUND FORCE IS 20N.YOU TAKE 50N-20N=30N.THE NET FORCE IS 30 NEWTON.
IF YOU ARE LAYING DOWN IN A LAKE ON YOUR BACK , THAT IS AN EXAMPLE OF BALANCED FORCES.
IF YOU ARE EXERTING 30N ON THE WATER AND THE WATER IS EXERTING 30N ON YOU,YOUR FORCE IS 0N.30N-30N=0N.

IF THEY ARE PUSHING YOU WITH 20N AND YOU ARE 10N THE FORCE WILL BE 1ON.20N-10N=10N.
THANKYOU AND BYE.
