Question

7. True of False. The Laws of Physics are the same in all inertial reference frames

(i.e., frames that move at constant relative velocity.) (a) True (b) False

8. True of False. Any reference frame that moves with constant velocity relative to

an inertial reference is also an inertial reference frame.

(a) True (b) False

9. From the theory of special relativity, energy = mc 2 . Thus, when a spring is

compressed, its potential energy increases and therefore the spring’s mass (a)

increases (b) decreases

Explanation / Answer

7.

this is True , the laws of physics are the same in all inertial reference frames.

8)

True , as there is no acceleration for the frame of reference relative to inertial frame of reference.

the other frame of reference is also inertial.

9)

as E = m * c^2

as the energy of spring is increasing,

the mass of spring will decrease.

the spring’s mass (b) decreases
