Conservation of momentum holds for observers in different inertial frames of reference if we use the classical definition of momentum. True False
Which of the following inertial reference frames are proper frames for the two events listed? Choose all that apply. RED FRAME: Event A happened at a different place than event B. ORANGE FRAME: Event C happened at (-7 m, 3 m, 4 m) and event D happened at (-7 m, 3 m, 5 m). YELLOW FRAME: The distance between where event E occurred and where event F occurred was 0 m. GREEN FRAME: A rocket was traveling at a constant...
15.52** (a) Suppose that the total three-momentum P = Σ p of an isolated system is conserved in all inertial frames. Show that if this is true (which it is), then the fourth component P4 of the total four-momentum P = (P, P) has to be conserved as well. (b) Using the zero-component theorem of Problem 15.35, you can prove the following stronger result very quickly: If any one component of the total four-momentum P is conserved in all frames,...
The energy of motion is called: Kinetic energy. potential energy, inertial energy. Power. In an inelastic collision: momentum is conserved. kinetic energy is conserved, both (a) and (b). If the velocity of a moving object is doubled and its mass is cut in half, the kinetic energy of the object is; remains the same, doubled quadrupled, cut in half. When the net work done on an object is speed of the object is me on an object is zero; the...
1. Which of these can be considered inertial reference frames? A: a car traveling on a straight road at a steady speed B: a car traveling on a straight road at increasing speed C: a car traveling around a curve at a steady speed both A and B both A and C both B and C A, B and C 2.A beam of light traveling to the right passes by an observer on...
A block of mass m1 rests on a frictionless inclined plane as
shown. The inclined plane, which has mass m2, rests on a
frictionless floor. Find the accelerations of both blocks with
respect to the inertial reference frame provided by the floor.
Hint: there are several different ways of doing this problem. You
may write the equation of motion of the top block in the
accelerating reference frame of the bottom block. You may instead
write everything in an inertial...
2. In an elastic collision, energy is not conserved. Where does it go? A) It is transformed into heat and also used to deform colliding objects. B) It is converted into potential energy. C) It is transformed into momentum such that momentum is conserved. D) All of the above. E) None of the above.
Time Dilation Time Dilation is a relativistic effect where time measured in two reference frames with relative motion is different, even when the clocks in both reference frames are initially synchronized. Clocks are synchronized when the same time is measured when their inertial reference frames are at rest relative to one another (meaning there is no relative velocity). When t0, the clocks in the two reference frames are synchronized at the origin. The Proper Time (To) is the time difference...
Which of the following is an inertial reference frame? Check all that apply. Check all that apply. a reference frame that is moving downward at a constant speed a reference frame that is motionless a reference frame that is rotating at a constant speed a reference frame that is moving upward at a constant speed
