Newton's Law of Motions

  • Newton's 1st Law of Motion: An object at rest remains at rest and an object in motion stays in motion
  • Newton's 2nd Law of Motion: F = ma (Force is equal to [constant] mass times acceleration)
  • Newton's 3rd Law of Motion: For every action, there is an equal and opposite reaction

Explanation:

Step 1: Define

Identify given variables.

m = 100 kg

a = 2 m/s²

Step 2: Find Force

  1. [Newton's 2nd Law of Motion] Substitute in variables:
    F = (100 kg)(2 m/s²)
  2. Simplify:
    F = 200 N

∴ it takes 200 Newtons of force to move a 100 kg object with an acceleration of 2 m/s².
