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 is needed to determine whether an object is in motion?
A Reference Point A reference point is needed to determine if an object is in motion.
What is the transfer of charge from one object to another by rubbing one is called?
Friction
Can an object get charged from stretching?
yes a object can charged by friction because by friction some atom loses electron gets positive charge on other hand some atoms accepts electron and gets negative charge
Friction is the frictional force needed to start an object at rest into motion.?
static

How is a positive charge usually given to a neutral object?
Friction will give a positive charge to a neutral object by conduction. This is done by rubbing two different materials together.
What type of friction is the frictional force needed to start on object at rest into motion?
Static
Why friction is problem?
Friction can be a problem as it slows down the movements of objects. It may also stop the movement of object and as such, a bigger force is needed to make the object move faster.
What friction is the frictional force needed to start an object at rest two motion?
static
What is required to get a stationary object moving?
An outside force is needed. If friction comes into play (which it likely will), the magnitude of the applied force must be greater than the force of friction acting upon the object in order for the object to move. FYI, the force of friction is equal to the coefficient of static friction times the normal force (equal to the weight of the object).
Can friction make object yes or no?
Friction can make object no.
Why is kinetic friction less than the limiting friction?
By my understanding, this is due to the fact that it is easier to keep a moving object in motion than it is to accelerate it from a resting position. When a force is exerted on a stationary object, acceleration relies on that force alone. However, with a moving body, the momentum of the object reduces the force needed to overcome friction.
