Newton (N) – The Unit of Force — Reading Comprehension

In science, force is a push or pull on an object. The unit used to measure force is the newton (N). This unit is named after Sir Isaac Newton, a famous scientist who developed the laws of motion, which explain how forces affect the motion of objects.

One newton is the amount of force needed to make a 1-kilogram object accelerate at 1 meter per second squared. That may sound complex, but it means that if you push something with a force of 1 newton, it will start to move—if it’s not too heavy or stuck.

Newtons help scientists and engineers describe exactly how much force is acting on an object. For example, when you lift a basketball, you are applying a force of about 5 newtons against gravity. Pushing a heavy box might take 100 newtons or more. If you know the force and the mass of an object, you can figure out how it will move using the equation:
 Force = Mass × Acceleration

The newton is an important part of understanding motion, energy, and work. It helps us measure how strong a push or pull is, whether it’s from gravity, a motor, or even a person.

Fun Fact: An average apple weighs about 1 newton! That means Earth pulls it toward the ground with a force of one newton due to gravity.
