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 number of classical simple machines?Six
2. What is the historical context?Crucial for monumental construction projects in ancient civilizations, enabling feats of engineering
3. How does a lever help us lift heavy objects?A lever uses a fulcrum to multiply force, so a small push can lift a heavy load, but the load moves a shorter distance than the push.
4. Why do cars use wheels and axles?Wheels and axles let the car turn and move smoothly, reducing friction and turning turning force into motion.

Mechanical Advantage: The ratio of output force to input force, indicating how much a simple machine multiplies force.
Work: The energy transferred when an object is moved over a distance by an external force.
Torque: A twisting or turning force that tends to cause rotation.
Kinematics: The branch of mechanics concerned with the motion of objects without reference to the forces that cause the motion.
