Chapter 5: Newton's Second Law of Motion—Force and Acceleration

MASS RESISTS ACCELERATION

Finding Acceleration
If you know the mass of an object and the forces acting on it, then you can determine its acceleration. This lesson from The Physics Classroom provides practice in finding an object's acceleration.

NEWTON'S SECOND LAW

Newton's Second Law
F = ma. OK, so what? Deepen your understanding of Newton's law of inertia using this interactive tutorial from The Physics Classroom.

FREE FALL EXPLAINED

The Elephant and The Feather
Which falls faster in air, an elephant or a feather? Don't think too hard! Check out this GIF animation from the Multimedia Physics Studios.

Free Fall and Air Resistance
When there is air resistance, more massive objects fall faster than less massive objects. This interactive tutorial from the The Physics Classroom will explain why.

FALLING AND AIR RESISTANCE

Sky Diving
The air resistance acting ona sky diver is affected by speed and cross-sectional area. Watch how these variables affect the sky diver in this GIF animation from the Multimedia Physics Studios.
