Key concepts students will learn:

  • Newton's Second Law of Motion states that net force equals mass times acceleration, where both force and acceleration are vectors.

  • When using Newton's Second Law, you need to identify the direction in which you are summing the forces.

  • A free body diagram shows the directions of forces, and Newton's Second Law helps to figure out the magnitudes of the forces and the acceleration of an object.
