1. A 4.0-kg block is lowered down a 37o incline a distance of 5.0 m from point A to point B
(Fig. 1). A constant horizontal force (F = 10 N) is applied to the block during motion. Th

Simple Harmonic Motion (SHM)
8.1 Equation of Motion
A vibrating system for which the restoring force is directly
proportional to the negative of the displacement ( F kx) is said
to exhibit Simple Harmonic Motion (SHM), and the system is
referred

Chapter 7
Rotation of Rigid Body
A rigid body is one that is nondeformable, i.e., the relative
positions of all particles making up
the object remain constant during
its motion.
It is much more convenient to work
with angular position, velocity and
accele

Magnetic Fields
Magnetic Poles
Every magnet, regardless of its shape, has two poles:
north pole and south pole.
Poles exert forces on one another:
Like poles (N-N,S-S) repel each other
Unlike poles (N-S) attract each o

Circular and Curvilinear Motions
Here we consider particles moving not along a straight line
the curvilinear motion. We first study the circular motion, a
special case of curvilinear motion. Another example we have
already studied earlier is th

There are two kinds of electric charges
Called positive and negative
Negative charges are the type possessed by
electrons.
Positive charges are the type possessed by protons

Force, Newtons Laws of Motion
Newtonian Mechanics is based on the laws
presented by Isaac Newton (1642-1727).
However,
at very large speeds (an appreciable fraction of the
speed of light c), Newtonian mechanics must be
replaced by Einsteins spec
