What is work? (ch7) - correct answer Work is done on an object by a force when the object moves through a distance. Work equation (no trig) (ch7) - correct answer W= F(vector)d(vector) Is work a vector quantity? (ch7) - correct answer No (it is a scalar quantity, although it is the product of two vector quantities) Scalar product of any two vectors A and B (ch7) - correct answer ABcosθ Work equation (trig) (ch7) - correct answer W=Fdcosθ What is kinetic energy? (ch7) - correct a...

A block of mass M on an inclined surface is attached to a spring of negligible mass, as shown. The other end of the spring is attached to a wall, and there is negligible friction between the block and the incline. The block is pulled to a position such that the spring is stretched from its equilibrium position. The block is then released from rest. Which of the following systems can be classified as a closed system? A system consisting of the block, spring, and Earth The total mechanica...

AP Physics 1 Unit 3 Progress Check MCQ Part B Scoring Guide 2023. Unit 3 Progress Check: MCQ Part B Page 1 of 30 A horizontal, circular track for running has four lanes, as shown in the figure. Various runners of different masses use the track. In each case, the center of mass of a runner follows a circular path around the track in one of the lanes. 1. Consider a runner in lane 1 with a speed and a runner in lane 4 with a speed , where the ratio of the speeds is . The radius of lane 4 is ...

AP Physics Unit 3 progress check Parts A&B (answered_2023.) AP Physics: Unit 3 Progress Check: MCQ Part A Planet X has a mass of MM and a radius of RR. Planet Y has a mass of 3M3M and a radius of 3R3R. Identical satellites orbit both planets at a distance RR above their surfaces, as shown above. The planets are separated by such a large distance that the gravitational forces between them are negligible. How does the magnitude of the gravitational force FYFY exerted by Planet Y on its sa...

AP Physics 1 Unit 6 Progress Check: Answered accurately 2023. What is the magnitude of the change in potential energy of the block-spring system when it travels from its lowest vertical position to its highest vertical position? 1/2k0(L1+L2)^2 The students conduct experiment 2 in which the same block is connected to the same spring on a horizontal surface. The spring is stretched a distance L2 beyond its natural length and released from rest, allowing the block-spring system to oscillate. F...
