1. What is Hooke's law? Give one example from real world where you can find its application. 2. How much force is needed to pull a spring with a spring constant of 50 N/m a distance of 10 cm? 3. A spring is pulled to 8 cm and held in place with a mass of 200 g. What is the spring constant of the spring? 4. What is a pendulum? Why does it follow SHM? If length of a pendulum is 1.2 m, what would be its time period? 5. If the length of the pendulum becomes 2m in the above question, what would be its new time period? If you increase mass, what will happen to time period? If you take the same pendulum with length of 2 m on Jupiter, what will be its time period? 6. A vertical spring is oscillating and has an amplitude of 2 cm. If mass hanging on this spring is 100 g and its spring constant is 50 N/m, find out its time period of oscillating. If you change the length of the spring, what will happen to its time period? If you take this spring to the moon, what will happen to its time period? 7. What is Elasticity? How many types of elasticity have you learn in chapter 10? Name them. What is Young's modulus? What is stress? What is Strain? What is relationship between spring constant (Hooke's constant) and Young's modulus? 8. A rubber band got extended to 15 cm when you apply a force of 10 N. If its original length was 10 cm, and its width and thickness were 4 mm and 0.5 mm, find out stress, strain, Young's modulus and spring constant of the rubber band. 1. What is Hooke's law?
