Understanding Balanced and Unbalanced Forces

The video tutorial explains the difference between balanced and unbalanced forces using a water balloon activity. When the balloon is pulled from one side, it moves due to unbalanced forces. When pulled from both sides, it deforms but does not move, demonstrating balanced forces. Unbalanced forces change an object's speed or direction, while balanced forces do not result in motion.

What is the initial setup for the activity to understand forces?

• A water balloon is placed on a rough surface.

• A water balloon is tied with threads and placed on a smooth surface.

• A water balloon is filled with air and placed on a smooth surface.

• A water balloon is tied with threads and placed on a rough surface.

What happens to the balloon when it is pulled to the left?

• It moves to the right.

• It stays in place.

• It moves to the left.

• It gets deformed.

What is the result of pulling the balloon from both sides?

• The balloon bursts.

• The balloon moves to the left.

• The balloon stays in place and gets deformed.

• The balloon moves to the right.

What are balanced forces?

• Forces that decrease the speed of an object.

• Forces that cause an object to move.

• Forces that do not cause any change in motion.

• Forces that increase the speed of an object.

How do unbalanced forces affect an object?

• They change the color of the object.

• They have no effect on the object.

• They change the shape of the object.

• They change the speed or direction of the object.
