1. Give examples of kinetic energy and potential energy in our everyday life. 2. 10 examples of potential and 10 examples of kinetic energy.
Answer (1)
Answer:Here are examples of kinetic and potential energy in everyday life: 1. Examples of Kinetic and Potential Energy in Everyday Life: - A roller coaster: When the coaster is at the top of a hill, it has potential energy (stored energy due to its position). As it rolls down the hill, it converts potential energy into kinetic energy (energy of motion).- A stretched rubber band: The stretched rubber band has potential energy. When released, it converts potential energy into kinetic energy as it snaps back.- A bouncing ball: When the ball is at its highest point, it has potential energy. As it falls, it converts potential energy into kinetic energy. When it hits the ground, it momentarily stops, then converts kinetic energy back into potential energy as it bounces back up.- Water in a dam: Water held behind a dam has potential energy due to its height. When released, the water flows through turbines, converting potential energy into kinetic energy, which is used to generate electricity.- A swinging pendulum: At the highest point of its swing, the pendulum has potential energy. As it swings down, it converts potential energy into kinetic energy. At the bottom of its swing, it has maximum kinetic energy, then converts it back into potential energy as it swings back up. 2. 10 Examples of Potential Energy: 1. A book on a shelf: The book has potential energy due to its position above the ground.2. A stretched spring: The spring has potential energy stored in its stretched state.3. A compressed gas in a can: The compressed gas has potential energy due to its compressed state.4. A bow drawn back: The drawn bow has potential energy stored in its stretched state.5. A battery: A battery stores chemical potential energy that can be converted into electrical energy.6. A car parked at the top of a hill: The car has potential energy due to its position.7. A roller coaster at the top of a hill: The roller coaster has potential energy due to its height.8. A diver standing on a diving board: The diver has potential energy due to their height.9. A rock perched on a cliff: The rock has potential energy due to its position above the ground.10. A hot cup of coffee: The coffee has thermal potential energy due to its temperature. 3. 10 Examples of Kinetic Energy: 1. A moving car: The car has kinetic energy due to its motion.2. A flying airplane: The airplane has kinetic energy due to its motion through the air.3. A flowing river: The water molecules in the river have kinetic energy due to their motion.4. A spinning fan: The fan blades have kinetic energy due to their rotation.5. A child on a swing: The child has kinetic energy as they swing back and forth.6. A running person: The person has kinetic energy due to their motion.7. A falling raindrop: The raindrop has kinetic energy as it falls.8. A rolling ball: The ball has kinetic energy due to its motion.9. A vibrating guitar string: The string has kinetic energy due to its vibration.10. A moving train: The train has kinetic energy due to its motion. I hope this helps!
