Answer 1

Answer:

friction is the resistance to motion of one object moving relative to another.

factors affecting friction are

1)smoothness and roughness of surface .

2)it is heavier and lighter substance.

Answer 2

$✔ \: Friction \: is \: the \: force \: resisting \: the \: relative \: motion \: of \: solid \: surfaces, \\ \: fluid \: layers, \: and \: material \: elements \: sliding \: against \: each other. \\ ✔ \: Friction \: is \: the \: resistance \: to \: motion \: of \: one \: object \: moving \: relative \: to \: another. \\ ✔ \: It \: is \: not \: a \: fundamental \: force, \: like \: gravity \: or \: electromagnetism. \\ ✔ \: Friction \: always \: works \: in \: the \: direction \: opposite \: to \: \\ the \: direction \: in \: which \: the \: object \: is \: moving, \: or \: \\ trying \: to \: move. \: \\ ✔ \: Friction \: always \: slows \: a \: moving \: object \: down. \\ ✔ \: example = > \\ ❥Rubbing \: both \: hands \: together \: to \: create \: heat. \\ </p><p></p><p>❥A \: sled \: sliding \: across \: snow \: or \: ice. \\ </p><p></p><p>❥Skis \: sliding \: against \: snow.</p><p></p><p>$
