Study Notes

Fundamental Concepts in Physics

The SI unit of mass is the kilogram (kg).
The gravitational force acts through empty space.
Newton's First Law states that an object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force.
The property of an object that specifies how much resistance it exhibits to changes in its velocity is called inertia.
The weight of an object is equal to the magnitude of the gravitational force exerted on it.
