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

1. 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.

Determining the Acceleration of an Object

2. Determining the Acceleration of an Object

Acceleration is a change in an object's state of motion. A few variables need to be identified to calculate an object's acceleration, but once we have those values, we can put them into a simple equation to find out how quickly or slowly an object's velocity is changing.

Determining the Individual Forces Acting Upon an Object

3. Determining the Individual Forces Acting Upon an Object

Objects constantly have forces acting on them whether they are moving or at rest. In this video lesson, you'll understand how to identify the individual forces acting on an object by reviewing the different types of forces and the use of free-body diagrams.

Air Resistance and Free Fall

4. 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.

Newton's Second Law & Uniform Circular Motion

5. Newton's Second Law & Uniform Circular Motion

Sure, Newton's Second Law of Motion works well in one dimension, but what happens when you put it on a curve? In this lesson, we'll see how the Second Law applies with respect to Uniform Circular Motion.
