Rubbing the balloon onto your hair or onto the wool fabric adds electrons to the balloon and causes the balloon to become negatively charged . Like charges repel (the two balloons, once charged, will move away from each other) and opposite charges attract (the paper will be attracted to the charged balloons.)
What charge does a balloon get when rubbing on hair?
Rubbing the balloon onto your hair or onto the wool fabric adds electrons to the balloon and causes the balloon to become negatively charged . Like charges repel (the two balloons, once charged, will move away from each other) and opposite charges attract (the paper will be attracted to the charged balloons.)
What charge does the balloon have positive or negative?
When you rub a balloon on a sweater, for example, some electrons come off and end up on the balloon. The fibers have lost electrons giving them a positive charge. The rubber gained electrons giving it a negative charge . Since electrons have a negative charge, the balloon now has a negative charge.
Does a negatively charged object have more electrons?
A negatively charged object has (more,fewer) electrons than on object that is neutral . ... Charge may be transferred from object to object, but it cannot be created or destroyed.
Is rubbing a balloon on your hair static electricity?
When one object is rubbed against another, static electricity can be created. This is because the rubbing creates a negative charge that is carried by electrons. ... Similarly, when you rub a balloon on your head it causes opposite static charges to build up both on your hair and the balloon.
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.
Why would a balloon attract your hair without touching it?
When a rubber balloon is rubbed against human hair, electrons are transferred from the hair to the rubber, giving the balloon a net negative charge, and leaving the hair with a net positive charge. As the balloon is pulled away, the opposite charge on the hair causes it to be attracted to the balloon.
What happen if two balloons were rubbed and placed together?
When you rub two things together you can move the negatively charged electrons from one material to another . ... When you rub both balloons, both end up with negative charge. Similar charges repel so the balloons push away from each other. You can even use one balloon to push the other around!
Why does rubbing a balloon charge it?
When you rub a balloon on your head, electrons move from the atoms and molecules in your hair onto the balloon. Electrons have a negative charge, so the balloon becomes negatively charged , and your hair is left with a positive charge.
What happens when you drag the balloon away from the shirt and let it go?
After rubbing the balloon on the shirt, what happens when you drag the balloon away from the shirt and let it go? The balloon moves towards the shirt . ... The shirt has more protons than electrons, while the wall has the same number of protons and electrons.
What does a negatively charged object have more of?
A negatively charged object has more electrons than protons . A neutral object has the same number of protons as electrons. Electrons or negative charges can flow freely from object to object.
Do 2 neutral objects attract?
Any charged object – whether positively charged or negatively charged – will have an attractive interaction with a neutral object. Positively charged objects and neutral objects attract each other ; and negatively charged objects and neutral objects attract each other.
What happens when a negatively charged object touches a neutral object?
When you bring a negatively charged object close to a neutral pith ball, ... These positive and negative charges attract the two closer and if they touch each other, positive charges get nullified and both bodies become negatively charged . Once both are negatively charged, they tend to repel each other.
What are 3 examples of static?
What are three examples of static electricity? (Some examples might include: walking across a carpet and touching a metal door handle and pulling your hat off and having your hair stand on end .) When is there a positive charge? (A positive charge occurs when there is a shortage of electrons.)
How do I make my hair stand up with static electricity?
The conductive metal discharges any static electricity that has built up on your skin creating a small electrostatic shock. To make your hair stand on end all you need to do is blow up a balloon and rub it on your jumper or hair .
How do I make my hair static electricity?
Steps: Rub the surface of the balloon with the cloth for 40 seconds . Hold the balloon a short distance above your head and watch your hair stick to it!
