nodic motion is a motion that repeats itself in equal intervals of time Cycle is one complete repetition of a periodic motion Application What I have learned Assessment Compute for the following. Show you solutions. Part I. 1. What is the magnitude of the force required to stretch a 20 cm-long spring, with a spring constar of 100 N/m, to a length of 21 cm? 2 What is the force needed to stretch a spring whose spring constant is 100 N/m by an amount of 3. What is the spring constant if a spring is stretch to 4 em in length with the use of 40 N? 4. A Hooke's Law spring was stretch to a length of 6.3 cm with a force of 65 N. Find the value of it spring constant. 5. A spring is stretch to 10 cm using a spring constant of 45 Nim. Find the magnitude of force. Part il.

A planet is in orbit as shown below. Where are the two possible locations for a sun? (plot the two possible locations) 2. In the picture below, the area in section A = the area in section B. a. According to Kepler's 2 law, which section takes more for the planet to travel? b. What does this mean about the relative speed of an orbiting body? 3. Kepler's first law states that a planet moves on an ellipse around the sun. where is the sun with respect to that ellipse? 4. A. could a planet move on a circular orbit? B. if YES, where would be the syn be with respect to that circle? PERIODIC MOTION Give five examples of periodic motion. 1
