Chapter 5 -Newton’s laws of motion

(a lovely picture of Atwood machine, this is a Pulley system . Get confident on Pulleys and pulley problems. These mainly have String Tension Force and you have to use Newton’s 2nd law of Motion that defines acceleration. This is described later in this course.)

This course gives a strong foundation to clearly understand Newton’s 3 Laws of Motion , and to apply them in practical problems.

1) Newton’s First Law of motion

2) Newton’s Second Law of motion

3) Inertial and Non-Inertial Frames, Fictitious (Pseudo) forces explained

4) Pseudo forces versus Inertia – what’s the difference – person sitting inside a car having acceleration

5) Newton’s Third law of motion.

6) ATWOOD Machine and formula for Acceleration (apply Newton’s 2nd Law of Motion)

7) Pulley Systems : having 2 pulleys, 2 Masses, and 2 ropes

8) Block sliding on an Inclined Plane – apply 1st and 2nd Law

9) Normal Reaction – horizontal plane

10) Concept of Action-Reaction pairs

11) Normal Reaction – Inclined plane

12) 3rd law application- Contact forces on a horizontal plane

13) Equation derivation of forces – Block moving on Inclined plane

14) Solved problems

Note: Difference between Interial and Non-Interial Frames is explained in detail – concept of Pseudo forces (Centrifugal force, and Coriolis Force)

Understanding the concept of “FRAMES of Reference” such as Inertial and Non-Inertial frames is usually difficult but very important. This abstract topic is also covered under the chapter “Rotation” or “Rotational Mechanics”.
