The Nature of Waves
The Nature of Waves:
Waves and Particles are two great concepts in classical physics.
Types of waves:
Mechanical (water, sound, seismic),

7.1 An Overview of Energy
Energy is conserved.
Kinetic Energy describes motion and relates to the
mass of the object and its velocity squared.
Energy on earth originates from the sun.

Abstract
The experiment examined how a free falling objects or projectiles are only
subjected to the force of gravity and no other forces. Neglecting air resistance all
objects accelerate at a rate of 9.80 m/s2 and when solving kinematic equations

Abstract
In this experiment, it was proven that the period of a simple pendulum is dependent on
the acceleration due to gravity. For the experiment, the period of the pendulum and angle of
displacement was recorded using the software system Capstone. The

STANDING WAVES ON A STRING
Introduction:
A wave is the propagation of a disturbance or energy. A wave is characterized by its
wavelength , the frequency of oscillation f (in Hz or 1/s = s1), and the wave speed v. These quantities
