Force, Mass, and Acceleration
Learning Objective
I can use Newton's second law to solve problems involving force, mass, and acceleration.
Key Concepts
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.
