Distinguish between balanced and unblanced force give effect of both types with suitable example
Answers
Balanced forces will cause no change in the speed of an object.
Balanced forces acting on an object in opposite directions and equal in strength, as shown in the arrows below, do not cause a change in the speed of a moving object.
Objects that are not moving will not start moving if acted on by balanced forces.
For example, in arm wrestling where there is no winner, the force exerted by each person is equal, but they are pushing in opposite directions. The resulting force (net force) is zero.
Or, in a tug of war, if there is no movement in the rope, the two teams are exerting equal, but opposite forces that are balanced. Again, the resulting force (net force) is zero.
Unbalanced forces are not equal, and they always cause the motion of an object to change the speed and/or direction that it is moving.
When two unbalanced forces are exerted in opposite directions, their combined force is equal to the difference between the two forces.
The magnitude and direction of the net force affects the resulting motion
This combined force is exerted in the direction of the larger force
For example, if two students push on opposite sides of a box sitting on the floor, the student on the left pushes with less force on the box than the student on the right side of the box
Or, if in a tug of war, one team pulls harder than the other, the resulting action (net force) will be that the rope will change its motion in the direction of the force with the greater strength/magnitude.
Hope you understand..
2. Example -when a ballon is pressed between hands , then balanced forces act on ballon due to which the shape of ballon changes
unbalanced force- if the resultant of all the forces acting on a body is not zero
2. Example - if there was no unbalanced force of friction and air resistance , then a moving bicycle would go on moving for ever
