Newton's Second Law of Motion

Newton's second law of motion states that the acceleration of an object is directly proportional to the force applied, and inversely proportional to its mass.

This means that if you apply a force to an object, the heavier the object is, the less it will accelerate. Conversely, if you apply the same force to a lighter object, it will accelerate more.


The formula for Newton's second law of motion is:

F = ma


  • F is the force applied to the object
  • m is the mass of the object
  • a is the acceleration of the object


Let's say you have a car that weighs 1000 kg. If you apply a force of 1000 N to the car, according to Newton's second law:

F = ma
1000 N = 1000 kg x a
a = 1 m/s²

This means that the car will accelerate at a rate of 1 m/s².


Newton's second law of motion is a fundamental concept in physics that helps us understand how objects move under the influence of forces.
