Hmm, friction maybe? I guess it depends on how fast she stopped?
Answer:
i think its false because
Explanation:
compounds are made of two or more atoms of <u>different</u> elements
Maybe this can help.
In mechanics, speed increase is the pace of progress of the speed of an article regarding time (acceleration). Speed increases are vector amounts (in that they have greatness and direction). The direction of an item's speed increase is given by the direction of the net power following up on that article. The size of an item's speed increase, as depicted by Newton's Second Law, is the consolidated impact of two causes:
the net equilibrium of all outer powers acting onto that item — size is straightforwardly relative to this net coming about force;
that article's mass, contingent upon the materials out of which it is made — extent is conversely relative to the item's mass.
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases.
