Force and motion: F = m × a

ASP video lesson, 5:58. ASP Domain 1: Mathematical Calculations

Newton's second law for the ASP exam: F = m × a, units, the velocity-change form, and a worked deceleration-force example, with every formula quoted from its source.

Included with every ASP pass, with captions, chapters and the full transcript. Every rule and number is cited on screen to its primary source.

What this lesson covers

In this lesson, you'll learn to: state Newton's second law as F equals m times a, identify the units of force, mass and acceleration, use the velocity-change form of the law, and calculate the force needed to decelerate a mass. Newton's second law ties three quantities together: force, mass and acceleration. For a constant mass, the law reduces to a mass times an acceleration: F equals m times a.
