What is the result of two objects with disimilar electrical charges touching?
An electrostatic discharge (ESD) occurs, to balance out the dissimilar electrical charges between the objects.
What is the coefficient of friction between a perfectly smooth body and a very rough body?
The coefficient of friction depends on the type of materials. Different pairs of materials have different cofficients of friction.
What is the name given to force that acts between materials that touch as they move past each other?
sliding friction or dynamic friction
What is the force when two materials rub together?
The force when two materials rub together is called friction. Friction is a resistive force that opposes the relative motion or tendency of motion between two surfaces in contact. The magnitude of the frictional force depends on factors such as the nature of the surfaces and the force pressing them together.
What does photovoltaic mean?
a photovoltaic effect is the affect when electromagnetic radiationfalls on a thin film of one solid deposited on the surface of a dissimilar solid producing a diffence in potential between the two materials
What happens when two objects with dissimilar electrical charges touch?
Electricity passes between them until the dissimilar charges become equal
What are the causes of sliding friction?
For example the cause of sliding friction of two materials is when the stress between the Materials is not equal to zero

What are friction materials?
friction materials are the one which help in inducing friction to a friction-less object, like brake lining on the brake shoe is used for inducing friction between the brake shoe and the inner rim of the wheel.
What scientific advances did Newton and Galileo make?
Galileo realized that the force of friction between materials opposes materials.
What is the name given to force that acts between materials that touch as they move past each other?
sliding friction or dynamic friction
What two materials helps a rider keep a frim grip?
The friction between the handlebars.
Where does the fuel for batterys come from?
Batteries generaly contain dissimilar materials and/or acids inside them in which the chemical reaction to balance the atoms between them supply the current.
What are the two factors that affect the friction force between two surfaces?
The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.
What is the difference between similar and dissimilar?
Similar means the same or alike, and dissimilar is the opposite of similar.
What is the use of friction board?
Friction boards are made of 4 different surface materials: cork, rubber, sandpaper, and Masonite. These boards are used to study friction between different types of material or matter. A device to measure friction.
