Understanding Relativity and Reference Frames

What is the principle of relativity as proposed by Albert Einstein?

• The laws of physics are the same in all inertial frames of reference.

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

• Time is absolute and the same for all observers.

• Gravity is a force that acts at a distance.

Which of the following is a consequence of the theory of special relativity?

• Objects can travel faster than the speed of light.

• Time dilation occurs for objects moving at high speeds.

• Mass is conserved in all reactions.

• Energy is not equivalent to mass.

In the context of relativity, what is a frame of reference?

• A point in space where time does not exist.

• A coordinate system used to measure the position and motion of objects.

• A hypothetical point where gravity is zero.

• A system where the speed of light is variable.

According to Einstein's theory of relativity, what happens to the mass of an object as it approaches the speed of light?

• It decreases to zero.

• It remains constant.

• It becomes infinite.

• It becomes negative.

What is the famous equation derived from the theory of relativity that relates energy and mass?

Which of the following best describes time dilation?

• Time moves faster for objects at rest compared to those in motion.

• Time moves slower for objects in motion compared to those at rest.

• Time is unaffected by the speed of an object.

• Time is the same for all observers regardless of their motion.

What is the term used to describe the bending of light around massive objects, as predicted by general relativity?

• Time dilation

• Gravitational lensing

• Doppler effect

• Quantum tunneling

Which of the following is NOT a postulate of Einstein's special theory of relativity?

• The speed of light is the same for all observers, regardless of their motion.

• The laws of physics are the same in all inertial frames of reference.

• Time and space are absolute and independent of each other.

• The speed of light is the maximum speed attainable.

What is the effect of gravity on time, according to general relativity?

• Gravity has no effect on time.

• Time runs faster in stronger gravitational fields.

• Time runs slower in stronger gravitational fields.

• Time is reversed in the presence of gravity.

Which experiment provided one of the first confirmations of the theory of general relativity?

• The Michelson-Morley experiment

• The double-slit experiment

• The observation of the bending of starlight during a solar eclipse

• The Rutherford gold foil experiment
