special relativity

Who proposed the theory of special relativity?

• Galileo Galilei
• Albert Einstein
• Isaac Newton
• Marie Curie

When does special relativity not apply?

• In low gravity
• At rest
• In a vacuum
• When things are moving very slow

state the first assumption of special relativity:

• The laws of physics are the same for all non-accelerating observers, regardless of their relative motion.
• The laws of physics are the same for all observers, regardless of their relative motion
• The laws of physics only apply to accelerating observers
• The laws of physics are different for all non-accelerating observers

State the second assumption of relativity

• The speed of sound is constant for all observers
• The speed of light changes based on the observer's location
• The speed of light is faster in a vacuum than in other mediums
• The speed of light in a vacuum is constant for all observers

If two events appear to occur at the same time to one person, do they have to be

simultaneous to someone else

• No, they do not have to be simultaneous to someone else.
• It depends on the events.
• Yes, they have to be simultaneous to someone else.
• No, they have to be sequential to someone else.

If something is moving faster will its measured length be

• inconsistent
• shorter
• the same
• longer

What is the concept of time dilation in special relativity?

• Time slows down for objects in motion

• Time speeds up for objects in motion

• Time remains constant for objects in motion

• Time stops for objects in motion

Explain the concept of length contraction in special relativity.

• Length increases for objects in motion

• Length remains constant for objects in motion

• Length decreases for objects in motion

• Length stops for objects in motion

What is the principle of relativity in special relativity theory?

• All motion is relative

• All motion is absolute

• All motion is constant

• All motion is variable

What is the principle of equivalence in special relativity theory?

• All motion is relative

• All motion is absolute

• All motion is constant

• All motion is variable
