Final answer:
When you rub a balloon on a sweater, the balloon becomes negatively charged while the sweater becomes positively charged. This creates an imbalance of charges, causing the balloon to stick to the sweater.
Step-by-step explanation:
When you rub a balloon on a sweater, the balloon becomes negatively charged while the sweater becomes positively charged. This is because electrons transfer from the sweater to the balloon, causing an imbalance of charges.
The opposite charges attract, so when you release the balloon, it moves towards the sweater and sticks.
This phenomenon is known as static electricity.
It occurs due to the transfer of charges between objects.
Static electricity is a topic studied in physics, specifically in the field of electromagnetism.
Understanding the behavior of charges and electric fields can help explain the interaction between the balloon and sweater.
