A large rock is motionless on a flat sidewalk. Which statement best explains why the rock remains motionless?

MRCORRECT has answered the question

Explanation:

There are no forces acting on the rock. The only force acting on the rock is directed toward the sidewalk

You have not provided any statements, but choose one that sounds like this: The rock remains motionless because of physics (or Newton's Laws of Motions)  or because no force is applied to the object to make it move.

Explanation:

"An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force."  - Newton's first law of motion.

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
