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 = s-1), and the wave speed v.
These quantities are related by the fundamental equation of wave mot
The purpose of the experiment was to examine the dependency of the period of a simple pendulum on
the acceleration due to gravity. The gravitational pull on the bob was manipulated but tilting the
pendulum at different angles and recording its pe
The purpose of this experiment is to predict the horizontal range of a projectile shot from
various height, angle, and initial velocity. The horizontal range varies when height, angle
and velocity change.
The projectile motion foll
Example: A Helicopter Blade
A helicopter blade has an angular speed of 6.50 rev/s and an angular acceleration of
1.30 rev/s2. For point 1 on the blade, find the magnitude of (a) the tangential speed
and (b) the tangential acceleration.

Method: refer to Physics lab manual 2: DC Circuits. There is no deviation from the
Calculation and analysis:
The purpose of this experiment was to determine, experimentally, the relationship
between the resistance and lengths of different wires such as brass, copper, and
aluminum. From the relationship between resistance, length, and cross-sectional ar
Any elastic material tends to return back to its original shape after experiencing
deformation. This means that elasticity implies a restoring force. For many elastic
substances the deformation is directly proportional to the restoring force
1.1 a) graph is showed on the other sheet, conclusion: not a straight line, but its too flat
that might look like a straight line.
b) Not a straight line, this is obviously a curve, when x<1, y is very large number,
