Acceleration is a change in velocity. That means acceleration can be a change in motion or speed. Acceleration can be thought of as an object's change in velocity over time.

Introduction to Newton's Second Law of Motion: F=ma. This video, which is suitable for high school students, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.'

The application of Newton’s Second Law is when you really understand what the net force equals mass times acceleration where both force and acceleration are vectors really means. Therefore, we introduce Newton’s Second Law and then do an example pro...blem.

Concepts: Mass (in terms of 2nd Law), Acceleration, Force, Newton, Force Equation ------------- Part of a Blended Classroom taught at Millard West High Schoo...

With the examples of a bicycle and a baseball player, an important rule of physics becomes apparent. Concept: Force = mass x acceleration. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video expla...ins the concept in simple and well illustrated way. Good for students of any elementary school level.[more]

This NASA video segment explores how Newton's second law of motion applies to aerospace. Viewers watch an instructor at NASA's National Test Pilot School as he defines the second law and demonstrates how to calculate a person's mass using the law. Th...ere is also a discussion about how people experience different g forces at the top and bottom of a roller coaster hill. Footage of the instructor in a fighter jet illustrates what it means to pull 2 and 4 g.[more]
