When you rub a piece of glass with silk (or a piece of hard rubber with fur), the friction transfers some of the electrons from one of the materials to the other. Moving electrons requires a certain amount of energy, they're not going to just hop over and create a separation of charges on their own: that's a higher potential energy. The energy is supplied by the motion.
What else can I help you with?
Friction is the frictional force needed to start an object at rest into motion.?
static
Is The force needed to overcome static friction usually less than that needed to overcome kinetic friction.?
True -It's "False"!
Do you have to touch and object to permanently give it a charge?
No, you do not need to touch an object to permanently give it a charge. You can induce a charge on an object through methods like friction, conduction, or induction. This charge can persist on the object even after you remove your contact.
What friction is the frictional force needed to start an object at rest two motion?
Static friction is the frictional force needed to overcome the initial resistance of an object at rest and set it in motion. This force is required to counteract the initial inertia of the object and is called static friction because it acts when an object is stationary.
What type of friction is Throwing?
Throwing involves dynamic friction, which is the type of friction that occurs between two surfaces in relative motion. When an object is thrown, the friction between the object and the hand provides the force needed to accelerate the object and give it velocity.

What factors contribute to the starting friction experienced by a moving object?
The factors that contribute to the starting friction experienced by a moving object include the roughness of the surfaces in contact, the weight of the object, and the force needed to overcome static friction.
What is the charge that stays on an object called?
The charge that stays on an object is called static charge or static electricity. It occurs when there is an imbalance of electric charges on the surface of an object due to friction or contact with other charged objects.
Why is it more difficult to charge an object by friction on a humid day than on a dry day?
Humid air contains more water molecules that can dissipate excess charge away from the object being charged, reducing its ability to accumulate charge. This makes it more difficult to charge an object by friction on a humid day compared to a dry day.
In a neutral object has been charged by friction to a charge of one pC what has happened to it electrically?
Approx. 6.24 x 106 electrons have rubbed either onto it or off of it during the friction, leaving the net charge on it unbalanced by 10-12 coulomb.
What is the electric charge that has accumulated on an object it referred to what?
The electric charge that has accumulated on an object refers to an excess or deficiency of electrons on the object's surface, leading to a net positive or negative charge. This accumulation of charge can be influenced by various factors such as friction, induction, or conduction.
True or false the force needed to overcome kinetic friction is useally greater than that needed to overcome static friction?
False. The force needed to overcome static friction is typically greater than that needed to overcome kinetic friction. Static friction is the resistance to motion when an object is at rest, while kinetic friction is the resistance to motion when an object is already in motion. Static friction requires more force to overcome because it is necessary to break the initial "stickiness" between the surfaces.
