How does the speed of light depend on an observer's frame of reference? a. the speed of light is faster when observed from a frame of reference that is not moving b. the speed of light is the same regardless of the frame of reference c. the speed of light is slower when observed from a frame of reference that moves close to the speed of light d. the speed of light depends on the acceleration of the frame of reference

The speed of light is the same in all frames of reference, regardless of the frame of reference or how it's moving.

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. 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.
