1.If you were in spaceship traveling at the speed close to the speed of light (with respect to the earth) you would notice that___________

your pulse rate is different than normal

your mass is different than normal

some of your physical dimensions were smaller than the normal

none of these effects occur

The speed of light (c) =

3 x 10⁸miles/hour

3 x 10⁸meters/second

3 x 10⁸kilometers/hour

none of these

The special theory of relativity was derived by:

Galileo

Newton

Einstein

Sitter

A postulate is something that is accepted as true at the beginning of a logical article.

True

False

How many postulates are there in the special theory of relativity?

The speed of light is constant in all frames of reference.

True

False

One of the most startling consequences of time dilation is that a moving clock ______________ relative to a stationary observer.

Speeds up

Slows down

We experience Einstein's Theory of Relativity in our everyday life when we use

Global Positioning System

Microwave ovens.

Toasters

Graphing Calculators

10.

When you approach a light source, the light from that source has a speed

greater than c.

less than c.

equal to c.

11.

We do not usually observe relativistic effects in our daily lives because

we are moving at speeds much less than c.

we are much larger than atoms.

we are much heavier than elementary particles.

we are much lighter than stars.

12.

The speed of light (c) =

186,282 miles per second

300,000,000 meters per second

3.0 x 10⁵km/sec (kilometers per second)

All answers are correct and equal to one another

13.

In what year did Einstein develop his theory of relativity?

1880

1905

1914

1921

14.

What astronomer was the firs to nail down a concrete measure of the speed of light?

Newton

Galileo

Romer

Plato

15.

What was the historical takeaway from the Michelson & Morley experiment?

It demonstrated there was no luminiferous aether.

It demonstrated light must move at the same speed regardless of reference frame.

It demonstrated light was a wave phenomena.

It demonstrated that the speed of light was relative.

16.

What is your position in your own reference frame?

$x=ct$

$x=vt$

$x=0$

$x=\frac{cv}{t}$

17.

In a spacetime diagram, suppose you have a worldline for some object moving relative to your frame of reference. If the object were moving twice as fast, what would happen to its worldline?

It'd have a slope twice as large as before.

It's have the same slope as before.

It'd have a slope half as much as before.

It'd have no slope and be a flat worldline.

18.

Which of the following is not a consequence of special relativity?

Moving objects appear shorter in length (thinner) than stationary objects.

Time appears to move at a different rate for objects moving relative to each other.

Mass and energy are the same thing: if you increase an object’s energy, you also increase its mass.

Nothing is certain; everything is relative.

19.

The term ‘relativistic’ refers to effects that are most easily

measured by stationary observers only.

observed when objects travel near the speed of light.

observed when objects move backward in time.

observed when any object moves.

20.

the relativistic (Lorentz) factor

length contraction
