Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is Kinetic energy recovery system known for?Enhances vehicle fuel efficiency and reduces emissions by minimizing energy waste
2. What is the core principle?Recuperation of kinetic energy during deceleration for subsequent use during acceleration
3. What is the primary storage technologies?Mechanical flywheels for kinetic energy storage or high-voltage batteries for electrochemical storage
4. What is a Kinetic Energy Recovery System (KERS)?KERS is a special system that saves the energy a car gives off when it slows down. It captures that energy and keeps it so the car can use it again when it speeds up, helping the car run faster and use less fuel.
5. How does KERS help a car use less fuel?When a car brakes, KERS takes the energy that would normally become heat and stores it. Later, when the driver needs more power, KERS gives that stored energy back to the wheels, so the car uses less new fuel.

Kinetic Energy: The energy an object possesses due to its motion, proportional to its mass and the square of its velocity.
Flywheel Energy Storage: A method of storing energy in a rotating mass, which can be accelerated or decelerated to store or release energy.
Continuously Variable Transmission (CVT): A transmission system that allows for a seamless and infinite variation of gear ratios, optimizing engine performance and efficiency.
Energy Recuperation: The process of recovering energy that would otherwise be lost, such as kinetic energy during braking.
