1. Oscillations & Simple Her 1. Oscillatory motion is a repeated motion in which an object repeats the sam the same movement over a it over and over about its 2. All oscillatory motions are _public : the motion repeats itself in a certain time. 3. All oscillations are_periodic rotation around the sun. _motion, however, all periodic motions are not oscillatory motion, e.g., earth's 4. Simple Harmonic Motions are oscillations about a single equilibrium. a restoring force brings the object toward Force is defection 5. Force-Displacement graph for a hanging mass-spring system is given. Find the stiffness of the spring in N/m. 6. According to Hooke's law (F, = -k. x) the restoring force( F) exerted by a spring on an Felasthe object is proportional to 7. In an oscillating mass-spring system, the velocity of the mass is greatest when the mass is at 8. The restoring force in a mass-spring system is F = -Kx . The restoring force in a simple pendulum is the force of gravity 10. Does the restoring force stay constant in the case of a swinging pendulum? 11. For a system in simple harmonic motion, is the time required to complete a cycle of motion. 12. The time period of a pendulum may be decreased by_ and 13. As the swinging bob of a pendulum moves farther from its equilibrium position, the pendulum's _increases. 14. If a given pendulum is moved from Earth to a location where the gravitational acceleration is greater than Earth's, the time period of the pendulum's swing will 15. Displacement - time graph of a pendulum's simple harmonic motion (also called sinusoidal motion in time) is given below. a. What is the period of this motion? b. Which point(s) are referring to equilibrium position? C. At what location velocity is maximum? d. At what location velocity is zero? e. At what location restoring force and acceleration are zero? f. At what location restoring force and acceleration are maximum? g. Approximately how much is the maximum displacement
