Grade 9 Module for distance or asynchronous learning
- 1. Activity 1 What’s In A. Identify whether the following has Potential or Kinetic Energy. Write the number in each corresponding column. If the activity is classified as potential energy, indicate the specific type of potential energy.
- 2. Activity 2: Fill in the Table Study the different activities which can be easily performed and then explain how energy is conserved. Activity 3: Modified TRUE or FALSE Write TRUE if the statement is correct and if FALSE change the underlined word to make the statement correct. ________1. The total mechanical energy of a given system is changeable. ________2. Conservation of mechanical energy refers to the total sum of the potential energy and kinetic energy of a system that remains the same as long as the only forces acting are conservative forces. ________3. In the law of conservation of energy, the decrease in potential energy is the same as the increase in kinetic energy. ________4. A thrown baseball has kinetic energy.
- 3. ________5. Potential energy is energy of motion. ________6. The faster an object moves, the smaller kinetic energy it has. ________7. When you are holding a book, energy is stored between the book and Earth; this type of energy is called potential energy. ________8. Mechanical energy is the total amount of potential energy and total amount of kinetic energy. ________9. The wind blowing through your hair is an example of potential energy. _______10. The “Law of Conservation of Mechanical Energy” states that the total mechanical energy in a system remains constant as long as the only forces acting are conservative forces.
