Learning Objective

I can use Newton's Second Law to solve problems involving force, mass, and acceleration.

  • 1

    Newton's Second Law explains that unbalanced forces cause objects to speed up, slow down, or change direction.

  • 2

    Newton's Second Law can be expressed with the equation: Resultant Force = mass x acceleration, where force is measured in Newtons, mass in kilograms, and acceleration in meters per second squared.

  • 3

    If the force from your arm is the same, but the mass of an object is much bigger, its acceleration will be smaller.
