Overview of Newton's Second Law of Motion

1. Overview of Newton's Second Law of Motion

Have you ever had to push a broken-down car? Hopefully, the answer is no but if you have, you definitely know that the lighter the car, the easier the job. In this lesson, we learn why that is the case.

Newton's Second Law of Motion: The Relationship Between Force and Acceleration

2. Newton's Second Law of Motion: The Relationship Between Force and Acceleration

This lesson defines Newton's second law of motion. Examples are used to illustrate how unbalanced forces cause objects to accelerate. The examples are used to practice calculating acceleration and force for objects in motion.

Air Resistance and Free Fall

3. Air Resistance and Free Fall

Through experiments by Galileo and Newton, we can understand why all objects in free-fall experience the same acceleration, ''g''. We can also see why air resistance affects a falling object's velocity and how this can lead to a falling object reaching a terminal velocity.

Overview of Force & Free-Body Diagrams

4. Overview of Force & Free-Body Diagrams

After completing this lesson, you will be able to explain what a free-body force diagram is, some of the rules associated with them, and what needs to be considered when drawing these diagrams.

How to Use Free-Body Diagrams to Solve Motion Problems

5. How to Use Free-Body Diagrams to Solve Motion Problems

The free-body diagram is a powerful way to analyze forces in a scenario. This lesson describes the rules you should follow when using a free-body diagram, and includes multiple examples modeling how to solve force problems.
