an interconnected network for delivering electricity from the producers to the consumers
|
What is Newton's 1st Law of Motion?
An object at rest, stays at rest and and an object in motion, stays in motion unless acted upon by an unbalanced force.
|
What is Inertia?
An object's resistance to changing its motion
|
What is Contact Forces?
Interactions between objects that touch ( example-baseball bat and ball)

What is "living off the grid"?
Living free of any reliance on a utility such as electricity, city water, city sewer systems, city garbage pickup,or natural gas provided by a utility company.
|
What is Newton's 2nd Law of Motion?
The acceleration of an object depends on two variables; the net force acting upon another and the mass of the object.
