What is friction ks2?
Friction is a force, the resistance of motion when one object rubs against another. Whenever two objects rub against each other, they cause friction. Friction works against the motion and acts in the opposite direction.
What is friction class 4th?
Friction is the resistance of motion when one object rubs against another. Anytime two objects rub against each other, they cause friction. Friction works against the motion and acts in the opposite direction.
What is the friction for Class 8?
Friction: The force that opposes the relative motion between two surfaces of objects when they come in contact. Frictional force always acts in a direction opposite to the direction of applied force. 2.
What is friction law?
Friction: Laws Of Friction The friction of the moving object is proportional and perpendicular to the normal force. The friction experienced by the object is dependent on the nature of the surface it is in contact with. Friction is independent of the area of contact as long as there is an area of contact.
What is friction very short answer?
Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
What does friction allow us to do?
Friction is the resistance to motion of two objects held against each other. Friction that allows us to walk depends on gravity to convert our mass to weight which holds our feet against the surface where static friction enables the soles of our shoes to push off against the surface of the Earth.
What are the main factors on which friction depends?
Roughness/smoothness of the sliding object
What are the problems with friction?
A number of problems can be caused by friction between two objects or materials. Since friction is a resistive force that slows down or prevents motion, it can be a nuisance, because it can hinder motion and cause the need for expending extra energy. Friction can also cause parts in contact to heat up and can cause parts in contact to wear out.
