Questions And Answers 2025 The figure shows an object moving from point B to point A and the gravitational potential energy of the object-earth system at different points along the trajectory. There are no other forces exerted on the object. Which of the following best describes the direction of the force extended on the 1 / 2

(diagram included in question) - C) The force is always directed downwards.The magnitude of the force associated with the gravitational field is constant and has a value F. A particle is launched from point B with an initial velocity and reaches point A having gained U0 joules of kinetic energy. A resistive force field is now set up such that is directed opposite the gravitational field with a force of constant magnitude 1/2F. A particle is again launched from point B. How much Kinetic energy will the particle gain as it moves from point B to point A? - B) 1/2Uo A particle moves under the influence of a conservative force. The graph shows the potential energy U as a function of position z. Which of the following graphs best shows the force F exerted on the particle as a function of x? (graph included in question) - D) (Since there is only an image, I will describe it / send you what it looks like) the first part is flat, then it goes from increasing to then decreasing. after it hits a certain point, it goes back up to increasing and then goes flat.For the section of the graph where 8 < x < 12, the equation for the potential energy as a function of position is U(x) = 1/2xˆ2 - 10x + 54. The force exerted on the particle when the particle is at x = 11 m is most nearly - B) - 1N In the lab setup above, block 1 is being pulled across a smooth surface by a light string connected across a pulley to a falling block 2. The pulley has negligible mass and friction. Students measure the mass of each block, the
