Ballistic Pendulum
Introduction:
A ballistic pendulum is used to measure the muzzle velocity of firearms.
Formulas:
Y2-Y1= L-Lcos
U= (m+M)g(Y2-Y1)=K
v1= [2K/(m+M)]1/2
Pi= (m+M)v1 = Pi
vo = v1= Pi/m= (m+M/m)v1
vo=[gx2/

Mass, Volume, Density
Introduction:
Key properties of mass, volume and density can be found by using basic measurements such as
length and diameter. This is fundamental because densities of different materials are comparable

Experiment 4:
Atwoods Machine
Introduction:
In this experiment we will measure acceleration due to gravity using Newtons Second
Law of Motion. Newtons Second Law can help determine the relationship between two masses

Friction
Introduction
Friction is an unwanted resistance to motion caused by one surface rubbing against another. In our experiment
we will deal with friction with the rubbing of a wooden block on another wood surfac

Free Fall Acceleration
Introduction
The acceleration of objects falling freely to the ground can be found using different formulas.
The first is the formula for average velocity. Once velocity is found, using distance and time,
accelerati

Experiment 2: Vectors
Introduction:
Force is an important concept in vector quantity in physics. Magnitude and direction of vectors,
their resolution vector and its components, and knowing how to add vectors, are all things that

Conservation of Momentum
Introduction:
The conservation of linear momentum can be measured using the velocities of two gliders on an
air track before and after collision.
Formulas Used:
Momentum P=mv

Work and Power
Introduction:
In physics, work is the application of a force to an object and the distance the object moves due
to the force. Mechanical work is defined as the magnitude of the applied fo

Uniform Circular Motion
Introduction:
The motion of an object in a circle with constant speed is known as uniform circular motion. The
purpose of the experiment is to find the force on an object moving in a uniform

Torques, Equilibrium, and Center of Gravity
Introduction:
To be in static equilibrium a rigid body must be in rotational static equilibrium. If the sum of the
torques is zero the object is in rotational equilibriu

Rotational Dynamics
Introduction:
The motion of an object that spins around a fixed axis can be observed using the rotational
analog of Newtons Second Law. Newtons Second Law relates to applying an action that causes
an objec
