waves UnI worksheet The diagram to the right shows a block attached to a Hookean spring. The block hangs at rest at position B. The block is raised to A and released. The lowest position it reaches is C. (During the oscillations, the spring is only being stretched, never compressed.) A The block then oscillates between positions A and C. Consider point B to be zero position, above B positive and below B negative. 1. Sketch a force diagram for the block at positions A, B, C, B, and A as it moves through a complete oscillation. Your arrow sizes should reflect which force is B the largest. 2. On the grid below, sketch a graph that you think reflects how the net force acting on the block changes as a function of time. Start your sketch at time = 0 which represents when the block was released at Point A. 3. Having completed the sketch of force vs. time, sketch the acceleration vs. time, position vs. time, and velocity vs. time A B B B A t i me time aco od t i me t i me vel 10 - @Modeling Instruction - AMTA 2015 Wi Oscillating Particle WS 1, v4.0
