Newton’s first law, 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.
Or in our case an object at rest will stay at rest until an outside force interferes.
I think it would be the fourth one
Answer: A chemical equation describes a chemical reaction. Reactants are starting materials and are written on the left-hand side of the equation. Products are the end-result of the reaction and are written on the right-hand side of the equation.
Explanation:
Theory is a description or explanation of a fact or occurrence obtained through experimentation, testing, observation whereas law is a statement which gives/tells relationship between entities under certain conditions.
<span>Kepler’s observation of planetary motion is a law not a theory because we assume certain things before deriving a mathematical expression. If you remember, the time period of a satellite moving around a planet is derived by assuming its orbit to be circular. We have "assumed the orbit to be circular" hence it is a law. Same with Einstein's relativity. Relativity is not a theory! You might have seen books titled "Einstein's Theory of Relativity" but it is "Einstein's law of Relativity" because he assumed certain axioms before putting forth his work. Hope this helped you.</span>
