Newton's first law of motion is often stated as: "An object at rest will stay at rest unless acted upon by an outside force. An object in motion will remain in motion at a constant speed and direction unless acted upon by an outside force." Motion, If an object is not ifluenced by any force.

We should never say that an experiment has proven something. The rutherford gold foil experiment led to the hypothesis that an atom's positive charge is concentrated in an incredibly small space at the atom's center. Why is energy from the sun renewable? The energy given out by the sun is constant and free of cost makingit renewable. Say for instance you have a litre of petrol, at theend of its use it does not replace itself, its gone forever unlikethe suns energy.
