A force that opposes any relative motion between the surfaces of two objects in contact is known as friction or frictional force.
Hope it helps
❤️ Friction is one of the force it oppose the motion of a body or the force which opposes the relative motion between two surfaces in contact is called " friction " .♥️ Frictional Force :-
❤️ Frictional Force refers to the force generated by two forces in contact and slide again .
1. is Friction but u have already written the answer
Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy
b)non living object
b)increase amount of heat
VERY SHORT ANSWER -
3. sliding friction
Hey Mark me as brainliast
can't sayincrese amount of heat
yes the answer given by arshchoudhary20 is right answer mark him as brainlist
Moving direction. Friction origin due to contact of two object and force applied by both. As nature also have many rough object that have large surface area that came into contact of
Objects and force applied by it like gravitational force take the other object into contact so, friction origin and slow down the moving object as it works against the moving direction.

is because magnetism is caused by preferential alignment of spins in the material, and their orientations keep due to thermal motions. the energy barrier is easier to overcome at temperatures, so magnetic strength gradually decays as you increase the temperature.
hope it ☝️
