Open the article and read it at the level above. Then answer the questions below in your own words.

https://smallwhale.org/articles/brake

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 the core principle?Inhibition of motion through absorption of kinetic energy, primarily via friction
2. What is the energy transformation?Converts kinetic energy into thermal energy (heat) through friction
3. What is a brake and why do we need it?A brake stops things from moving by using friction. It helps keep cars, bikes, and machines safe.
4. How does a brake use friction to stop a car?When you press the brake pedal, the brake pads press against a rotor or drum, rubbing together. The rubbing turns the car's motion into heat, which slows it down.

Kinetic Energy: The energy an object possesses due to its motion, proportional to mass and velocity squared.
Friction: A force opposing relative motion between surfaces in contact, dependent on surface properties and normal force.
Hydraulic Actuation: The use of pressurized fluid to transmit force, commonly employed in automotive brake systems.
Coefficient of Friction: A dimensionless scalar value representing the ratio of the force of friction to the normal force between two surfaces.
