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 SI unit for?Torque (or moment of force)
2. What is the dimensional formula?M L² T⁻² (Mass × Length² × Time⁻²)
3. How does a Newton metre measure twist?It tells us how much force, applied at a distance, makes something turn. One Newton of force applied one metre away from the pivot makes one Newton metre of torque.
4. Why is it called a Newton metre?It is named after Sir Isaac Newton, who helped explain how forces work, and the "metre" part shows it uses the metric distance unit.

Torque: A measure of the effectiveness of a force in causing or changing rotational motion.
Moment of Inertia: A measure of an object's resistance to changes in its rotational motion.
Angular Acceleration: The rate at which an object's angular velocity changes over time.
