How does force of friction move when compared to the movement of the object it is working upon?

Select one

in the same direction

in the opposite direction

in a circular direction

in a perpendicular direction

In the opposite direction

Explanation:

Friction is a type of force that resists the motion of the other object causing it to slow down, and in most cases the force acts in the opposite direction to the motion.

a. they are both space stations

pls mark as brainliest.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
