Motion
A ________ has a magnitude and direction.
A vector has a magnitude and direction.
What is the formula for acceleration?
a= (vf-vi)/ t
What is Newton's first law of motion?
The law of inertia; an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by a force.
Energy is measured using which units?
Joules
An object or material that allows the flow of charge and heat in one or more directions.
Conductor
