Question is :
Write an activity to demonstrate balanced and unbalanced force . ( Don't copy )

Answer 1

Balanced forces will cause no change in the speed of an object.

1. 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.
2. Objects that are not moving will not start moving if acted on by balanced forces.
3. 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.
4. 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 (small arrow) on the box than the student on the right side of the box (long arrow).
• The resulting action (net force: smaller arrow to the right of the = shows that the box will change its motion in the direction of the greater force as shown below:

Answer 2

HEY THERE !!!

To determine if the forces acting upon an object are balanced or unbalanced, an analysis must first be conducted to determine what forces are acting upon the object and in what direction.

If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced.
An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.
