Since the laws of physics are the same in every reference frame, an object must have the same kinetic energy in all inertial reference frames.

Since the laws of physics are the same in every
reference frame, an object must have the same
kinetic energy in all inertial reference frames.

1. True
2. False

2
Since the laws of physics are the same in every
inertial reference frame, an interaction between
objects must be observed to conserve energy in
all inertial reference frames.

1. True
2. False

3
Since the laws of physics are the same in every
inertial reference frame, if you perform
identical experiments in two different inertial
reference frames, you should get exactly the same
results.

1. True
2. False
