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. Who discovered Force?Sir Isaac Newton, formalized in his 1687 publication 'Principia Mathematica'
2. What is the SI unit?Newton (N)
3. What is the nature?A vector quantity, possessing both magnitude and direction
4. How do we measure force?Force is measured in Newtons (N). It is written as a vector, meaning it has a direction and a magnitude.
5. Why is Newton's second law important?Newton's second law says F = ma, which tells us that the force on an object equals its mass times its acceleration. It lets us calculate how objects will move.

Vector Quantity: A physical quantity that has both magnitude (size) and direction.
Classical Mechanics: The branch of physics describing the motion of macroscopic objects under the influence of forces.
Quantum Mechanics: The branch of physics describing the behavior of matter and energy at the atomic and subatomic levels.
