## Why does a balloon stick to a sweater after rubbing it?

So the balloon ends up with a net negative charge, and the sweater or hair, having lost negative charges, gets a net positive charge. And since opposite charges attract, the balloon will stick to the sweater or to someone’s hair after being rubbed on it.

## What happens when you rub a balloon on a wool sweater?

Wool is a conductive material, which means it readily gives away its electrons. Consequently, when you rub a balloon on wool, this causes the electrons to move from the wool to the balloon’s surface. The rubbed part of the balloon now has a negative charge.

## Why do balloons stick?

This tendency is why we have static electricity. When two objects – such as your hair and the balloon – rub together, one loses some of its electrons to the other. The negatively charged balloon is then attracted and will “stick” to the object.

## What happens when you rubbed two balloons on the sweater?

When rubbing a balloon with a wool cloth, it puts negative charges on the balloon. Negative charges attract to positive charges. When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.

## How can you make two balloons stick to a sweater?

By rubbing the balloon on a sweater, you can transfer negative charges onto the surface of the balloon. If the wall has positive charges on its surface, the opposite charges attract one another, causing the balloon to cling to the wall.

## What happen when you bring the balloon near your hair after rubbing it?

Rubbing the balloon onto your hair or onto the wool fabric adds electrons to the balloon and causes the balloon to become negatively charged. Your positively charged hair is attracted to the negatively charged balloon and starts to rise up to meet it.

## How will 2 positive charges react?

If two positive charges interact, their forces are directed against each other. (The same occurs with two negative charges, because their respective forces also act in opposite directions.) The electric field and resulting forces produced by two electrical charges of the same polarity. The two charges repel each other.

## When a balloon is given a negative charge by rubbing it with a wool jacket?

When you rub a balloon with a wool cloth, the balloon captures electrons from the wool, leaving the balloon with a negative charge and the wool with a positive charge. If both balloons are rubbed with wool, they will both have same charge (negative) and therefore will repel each other.

## Why can you make a goal without hitting the puck?

the higher the charges are, the farther away the balloons will move away from each other. why can you make a goal without hitting the puck? the charges would move away from each other.

## How do you get balloons to stick to the wall?

To start, blow up your balloons (to cover a wall, you’ll need about 70 or so ). Next, place a removable glue dot on the side of each balloon, peel away the backing, and start placing them on the wall. Repeat these steps until you’re happy with your creation. Bonus tip!

## What happens to the stream of water when you hold the charged balloon next to it?

When you bring the charged balloon near to the water it pushes electrons away, leaving a positively charged area which is attracted to the balloon. The water coming from the tap is neutral with positive and negative charges. This positively charged water is attracted to the balloon so the stream is deflected.

## What happens to the positive charges in the wall when you move the balloon near it?

The positively charged fibers are now attracted to the negatively charged balloon. When you bring the balloon near a little piece of paper, the negative balloon repels the electrons in the paper so part of the paper near the balloon is positive. Since positive and negative attract, the paper moves toward the balloon.

## What will happen when you move the yellow balloon closeto but not touching the sweater?

What happens when the balloon is close to, but not touching the wall? The electrons in the wall repel because of the negatively charged balloon, exposing the positively charged nucleus, allowing the balloon and wall to attract each other. (Electrons repel to the back of the wall).

## What will happen when two oppositely charged balloons are brought close together?

We have now observed the fundamental behaviour of charges. In summary, we can say: If two negatively charged objects are brought close together, then they will repel each other. If two positively charged objects are brought close together, then they will repel each other.

## What happens when you touch a metal doorknob after rubbing your shoes on the carpet?

Sometimes by walking on carpet for example, friction causes the rubber in your shoes to pick up electrons and then when you touch a metal doorknob (a conductor) you will feel a shock as the electrons jump from your body into the doorknob.
