Kinetic energy meaning and example
Answer (1)
Answer:Kinetic energy is the energy of motion. It's the energy an object possesses because of its movement. The faster an object moves, the more kinetic energy it has. Here's a breakdown: - Kinetic comes from the Greek word "kinesis," meaning "motion."- Energy is the capacity to do work. Examples of Kinetic Energy: - A rolling ball: The ball is in motion, so it has kinetic energy.- A running person: The person's body is moving, so they have kinetic energy.- A flying airplane: The airplane is moving through the air, so it has kinetic energy.- A flowing river: The water molecules are moving, so the river has kinetic energy.- A spinning top: The top's rotation is a form of motion, so it has kinetic energy. The formula for kinetic energy is: KE = 1/2 * mv² Where: - KE = Kinetic Energy- m = Mass of the object- v = Velocity of the object Key Points: - The more massive an object is, the more kinetic energy it has at a given velocity.- The faster an object moves, the more kinetic energy it has.- Kinetic energy is a scalar quantity, meaning it has magnitude but no direction. I hope this help!
