Question

wich type of friction can best be described as the force between objects that are moving (static friction)(rolling friction )(kinetci friction)(sliding friction

Answer 1

The answer is kinetic friction.

Answer 2

Kinetic friction

Step-by-step explanation:

When body is in rest then static friction force will act in opposite direction .Ans this force will given as follows

`fr_s=\mu _(st)mg`

`\mu _(st)\ is\ the\ coefficient\ of\ static\ friction`

When body is in motion then kinetic friction force will act in opposite direction .Ans this force will given as follows

`fr_k=\mu _(k)mg`

`\mu _(k)\ is\ the\ coefficient\ of\ kinetic\ friction`

When body rolls then rolling friction will act.

When body will slid then sliding friction will act.
