The outer surfaces of all substances encountered in our daily lives are covered in electrons. When two surfaces are rubbed against each other, electrons may be transferred from one surface to the other, creating a static charge on each of the substances, one positive and the other negative.

What kind of energy is a scout rubbing sticks together to start a fire?
The energy produced by a scout rubbing sticks together to start a fire is primarily mechanical energy, which is converted into thermal energy (heat) through friction. As the sticks are rubbed together, the heat generated can ignite the combustible material nearby, resulting in a fire. This process exemplifies the conversion of mechanical work into thermal energy.
Why does static electricity charge with wool?
Static electricity is the buildup of electrical charges on the surface of some object or material. Static electricity is usually created when materials are pulled apart or rubbed together, causing positive (+) charges to collect on one material and negative (−) charges on the other surface. Results from static electricity may be sparks, shocks or materials clinging together.
Explain two ways the vertebrae column reduces shock when jumping?
1. The cartilage forms a cushion-like covering, spreading the load in the backbone which prevents the shock between bones. 2. The cartilage produces a slippery surface at the end of bones to reduce the friction when they are being rubbed together.
The calor a mineral leaves when it is rubbed across a plate?
Streak is the color of the finely powdered mineral when rubbed across a plate. Streak is one of the physical properties of minerals used to identify which specific mineral it is. Some minerals leave a completely different color streak than the original color of the whole mineral.
How do you use the word genie in a sentence?
When Aladdin rubbed the lamp the genie came out and gave him three wishes. Or, our Genie garage door opener is 40 years old.
Why do two different substances build up static charges when rubbed together?
When two different substances are rubbed together, electrons can be transferred between them due to differences in their electron affinity. This transfer of electrons creates an imbalance of positive and negative charges, leading to a buildup of static electricity on the surfaces of the substances.
What kind of materials can become electrically charged when they are rubbed together?
When certain materials are rubbed together, they can become electrically charged. These materials are typically non-metallic and include substances like rubber, plastic, and fur.
When the glass rod is rubbed to the silk the electrons are transfered?
both get charged but with charges of opposite nature
When a diamond and silver are rubbed together the diamond makes a scratch in the silver. What does this tell you about the two substances?
diamond is harder than silver
What atomic particle can get rubbed off?
You think probable to electrons.
Cocaine i have never done it and it is showing up in urine tests my man does it can it be transfered through him?
Transfered how? This drug is not sexualy transmitted, so unless you were kissing him after he rubbed it on his gums your lying.
What two stones can be rubbed together to make fire?
Flint and Steel can be rubbed together to make fire.
How do materials become charged when rubbed together?
By electrons
What theory explains why objects become warm when rubbed together?
The theory that explains why objects become warm when rubbed together is called frictional heating. When two objects are rubbed together, the friction between them causes kinetic energy to be converted into thermal energy, which results in heating of the objects.
What can occur when two insulators are rubbed together?
static electricity
What caused the earthquake in sanfransico?
the conservative boundres rubbed together.
What is a subatomic particle that can be rubbed off an atom?
An electron is a subatomic particle that can be rubbed off an atom. Electrons are negatively charged particles that orbit the nucleus of an atom, and they can be transferred between atoms through processes like friction, leading to static electricity. When electrons are removed from an atom, it becomes positively charged, forming a cation.
