Which is not true of Newton's ideas?

Time between two events depends on which F.O.R. you are in.

Answers

1
Which is not true of Newton's ideas?
Time is absolute
Laws of physics apply in all F.O.R.s
Time between two events depends on which F.O.R. you are in.
Inertial frames of reference are non-accelerating
2
When travelling towards a light source what do you observe?
You add your speed onto c
c is lower
Increase in light frequency
No change
3
A cyclist (40 km/hr) drops a ball. Ignore air resistance-the balls path to the cyclist appears:
Backward
Stationary
Straight down
Down and backward
4
What is an inertial frame of reference?
A stationary frame of reference
An accelerating frame of reference
Any frame that is not undergoing acceleration.
Where ever the observer is
5
Which of these did Maxwell not conclude?
The ether provides an absolute F.O.R.
Light travels at c in a vacuum
Light is an EM wave
Light travels through an ether
6
Easy one first. What is the speed of light
2.78x10^8m/s
3x10^8km/h
3x10^8m/s
3km/h
7
Two cars travel toward each other at 100km/hr. An observer in car A measures car B's speed as:
100 km/hr
150 km/hr
200 km/hr
Can't be calculated
8
What was Einstein's second postulate that he based his theory on?
There is a universal zero velocity
Previous calculations were to elegant to ignore
There is no absolute velocity
Speed of light is a constant
9
What was Einstein's first postulate that he based his theory on?
Previous calculations were to elegant to ignore
There is a universal zero velocity
Speed of light is a constant
The laws of physics are the same in all inertial frames
10
The desired result of the Michelson and Morley experiment was:
That light was an electro-magnetic wave.
That light traveled through a medium called ether.
That light created interference patterns.
That the speed of light was constant in a vacuum.
