Choose the BEST answer to the following:
In his special theory of relativity, Einstein stated that the laws of physics are
(a) different in different situations.
(b) common sense applied to microscopic and macroscopic things.
(c) the same in all frames of reference.
(d) the same in all uniformly moving frames of reference.
Einstein's general theory of relativity successfully challenged Newton's framework of space and time. Is this true or false?
The special theory of relativity is based on two principles: the relativity principle, which states that the laws of physics are the same in all inertial reference frames, and the principle of the ___ of the speed of light, which states the the speed of light in empty space has the same value in all inertial reference frames. What is the blank?

- You may have an image of Sir Isaac Newton sitting under a tree and after being hit on the head by an apple he suddenly "discovered" the Law of Universal Gravitation. In fact, the theory was a result of years’ worth of research, which in turn was based on centuries of accumulated knowledge. He is credited with determining that the following relationship is universal. The gravitational attraction between two objects varies jointly with their masses (m1 and m2) and inversely with the square of the distance (d) between them. By what percent does the force of gravitational attraction change if one mass is increased by 20%, the other mass decreased by 20%, and the separation is reduced by 25%?arrow_forwardEinstein's mass-energy equation is E=mc 2 , where mass is in kilograms and the speed of light is 3.00×108m/s. The unit of energy is the joule (4.184J=1cal;1000cal=1kcal,1J=1kg⋅m2/s2). 1) Calculate the energy released, in calories, when 1 g of matter is converted to energy, then calculate the energy released, in kilocalories, when 1 g of matter is converted to energy. 2)arrow_forwardChoose the BEST answer to the following: What Einstein discovered about space and time is that they (a) are separate entities. (b) are parts of one whole. (c) follow an inverse-square law. (d) are special to space travelers.arrow_forward
- With regard to reference frames, how does general relativity differ from special relativity?arrow_forwardIf you use an Earth based telescope to project a laser beam onto the moon, you can move the spot across the moon's surface at a velocity greater than the speed of light Does this violate modern relativity? (Note that light is being sent from the Earth to the moon, not across the surface of the moon.)arrow_forwardIt is said that Einstein, in his teenage years, asked the question, What would I see in a mirror if I carried it in my hands and ran at the speed of light? How would you answer this question?arrow_forward
- If general relativity offers the best description of what happens in the presence of gravity, why do physicists still make use of Newton’s equations in describing gravitational forces on Earth (when building a bridge, for example)?arrow_forwardWhich of Einstein’s postulates of special relativity includes a concept that does not ?t with the ideas of classical physics? Explain.arrow_forwardAssume that the mass of the Sun is 75% hydrogen and that all of this mass could be converted to energy according to Einstein’s equation E=mc2 . How much total energy could the Sun generate? If m is in kg and c is in m/s, then E will be expressed in J. (The mass of the Sun is given in Appendix E.)arrow_forward
- according to the universal gravitational Newton's law, the gravity exists between any two massed objects at a certain distance. Why could you not sense the gravity from your neighboring classmate who is sitting at , e.g. 1 meter away from you?arrow_forwardThe active gravitational mass (m^) of a particle is an attribute that enables it to establish a gravitational field in space, whereas the passive gravitational mass (m") is an attribute that enables the particle to respond to this field. (a) Write Newton's law of universal gravitation in terms of the relevant active and passive gravitational masses. (b) Show that the third law of motion makes it unnecessary to distinguish between active and passive gravitational mass.arrow_forwardSuppose that a planet were discovered between the Sun and Mercury, with a circular orbit of radius equal to 2/3 of the average orbit radius of Mercury. What would be the orbital period of such a planet? (Such a planet was once postulated, in part to explain the precession of Mercury's orbit. It was even given the name Vulcan, although we now have no evidence that it actually exists. Mercury's precession has been explained by general relativity.)arrow_forward
