Momentum, Conservation of Momentum
The collision of two carts on a track can be described in terms of momentum conservation and,
in some cases, energy conservation. If there is no net external force experienced by the system

Why everyone in this class is attracted to everything else.
Every object around you is attracted to you. In fact, every object in the galaxy is
attracted to every other object in the galaxy. Newto
Lab #13 (Mini)
Rotational Equilibrium. Torque.
Purpose: To investigate the principle of balanced torques.
Materials: Meter stick, fulcrum to support meter stick, four clamps and hangers, set of
Theory: A crowbar is perhaps the most famili
A classic experiment in physics is the Atwoods machine: Two masses on either side of a pulley
connected by a light string. When released, the heavier mass will accelerate downward while
the lighter one accelerates upward at t
The Centripetal Force
Purpose: To figure out how much force is required to keep a body of known mass
revolving in a circular path.
Apparatus: Centripetal force apparatus, electronic scale, meter stick, stopwatch.
Theory: When a given mass
Purpose: This lab is designed to see if you can apply some of the ideas we have been
talking about in class. The applications will concern kinematics in two dimensions.
List of Materials: Ballistic Pendulum Apparatus, plas
When you solve physics problems involving free fall, often you are told to ignore air resistance
and to assume the acceleration is constant and unending. In the real world, because of air
resistance, objects do no
A swinging pendulum keeps a very regular beat. It is so regular, in fact, that for many years the
pendulum was the heart of clocks used in astronomical measurements at the Greenwich
There are at
Lab 07 (Mini)
Purpose: To investigate the two types of friction and to measure the coefficient of
friction for each type.
Apparatus: Flat board, wooden block, set of weights, spring scale.
Theory: Friction results when the surfaces of two
Picket Fence Free Fall
We say an object is in free fall when the only force acting on it is the earths gravitational force.
No other forces can be acting; in particular, air resistance must be either absent or so small as to
be ignored. When
Energy of a Tossed Ball
When a juggler tosses a bean ball straight upward, the ball slows down until it reaches the top
of its path and then speeds up on its way back down. In terms of energy, when the ball is
released it has kin
One of the most effective methods of describing motion is to plot graphs of distance, velocity,
and acceleration vs. time. From such a graphical representation, it is possible to determine in
what direction an o

Suggested Equipment: Force table with center pin, strings, hangers (3), assorted masses,
Simple Machines. Pulleys.
Objectives: To assemble and manipulate a variety of fixed and moveable pulley systems.
