Give at least 2 example of work energy and power
Answer (2)
Answer:Here are 2 examples of work, energy, and power: Example 1: Lifting a Weight - Work: When you lift a weight, you are doing work against gravity. The amount of work done is equal to the force you exert (the weight of the object) multiplied by the distance you lift it.- Formula: Work = Force x Distance- Energy: The energy used to lift the weight is stored as potential energy. The higher you lift the weight, the more potential energy it has.- Formula: Potential Energy = Mass x Gravity x Height- Power: The rate at which you lift the weight is called power. It is equal to the work done divided by the time it takes to do the work.- Formula: Power = Work / Time Example 2: A Car Accelerating - Work: When a car accelerates, the engine does work to increase the car's kinetic energy. The work done is equal to the change in kinetic energy.- Formula: Work = Change in Kinetic Energy = 1/2 * Mass * (Final Velocity)^2 - 1/2 * Mass * (Initial Velocity)^2- Energy: The energy used to accelerate the car is stored as kinetic energy. The faster the car moves, the more kinetic energy it has.- Formula: Kinetic Energy = 1/2 * Mass * Velocity^2- Power: The rate at which the car accelerates is called power. It is equal to the work done divided by the time it takes to do the work.- Formula: Power = Work / Time Let me know if you'd like more examples or have any other questions!
