9. Use the words from the list instead of the underlined ones to express the

same ideas.

Contributes to, precisely, steady, equal or exceed, doing away completely with,

rotating, intertwined with one another, viewed, singled out, unprovable,

foundation, were aware of, consistent with, did not satisfy, are simultaneous.

1. Frames

turning round a fixed point

are noninertial frames.

2. Both Galileo and Newton had a good understanding

what we now call

relativity principle.

3. Galilean-Newtonian relativity involves certain assumptions that can’t be

proved that make sense from everyday experience.

4. In what reference frame does light have exactly

the value predicted by

Maxwell?

5. In his famous 1905 paper Einstein proposed abolishing

the idea of ether.

6. It appeared that Maxwell’s equations disagreed with

the relativity principle.

7. Physicists considered

the material world in terms of the laws of mechanics.

8. The second postulate is in agreement

with the first.

9. They chose

one reference frame that was better than any other.

10. The time interval between two events, even if two events happen exactly at

the same time, depends on the observer’s reference frame.

11. The speed of an object cannot be the same as or greater than

the speed of

light.

12. The two postulates form the basis

of Einstein’s special theory of relativity.

13. Uninterrupted

net force applied to an object adds to increasing its speed.

14. The concepts of space and time are now firmly joined together

.

10. Fill in the correct word from the list below.

View, denominator, rocked, comprehensive, contradictions, complications,

inconsistencies, impact, permeated, implies, take into account, obey, accurate,
