PHYSICS 415 Unit 1 Progress Check MCQ Rock X is released from rest at the top of a cliff that is on Earth. A short time later, Rock Y is released from rest from the same location as Rock X. Both rocks fall for several seconds before landing on the ground directly below the cliff. Frictional forces are considered to be negligible. Which of the following graphs best represents the vertical displacement of Rock X as a function of time starting from immediately after the rock is released from r...

AP Physics 1 - Unit 2 Progress Check: MCQ Part A&B (2023) If the mass of block B is 2kg, the gravitational force exerted on block B is most nearly which of the following? 20 N The two blocks eventually stop and reverse direction. Which of the following graphs best predicts the acceleration of block A as it moves up and down the rough, inclined surface? Assume that the positive direction points down the slope. -------- ---------- (In Quadrant 1) A 5kg object is released from rest near the surface...

AP Physics 1 Unit 4 Progress Check A and B Answered 2023. AP Physics 1 Unit 4 Progress Check 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 ...

AP Physics 1 Unit 5 Progress Check A Block X and block Y are tied together by a rope. The system containing block X and block Y is released from rest on a ramp, as shown in the figure. Block Y has a smaller mass than block X. Which of the following claims is correct regarding the momentum of the system containing only block X and the system that contains block X and block Y? An experiment is conducted in which a cart travels across a horizontal surface and collides with a wall. Data collec...
