Friction on incline surface
To measure the coefficient of static and kinetic friction by application of Newtons law.
Introduction and Theory:
The reaction force of a surface to an object
Standing Waves Lab
A standing wave pattern is created by an incoming wave constructively interfering with a reflected
wave. These interference points can occur at multiple places as demonstrated in class. In this lab, we
will attempt to create the first f
Measurement of Acceleration on an Inclined Plane
(1) Incline the track by a few degrees by placing a book under one end.
(2) Place two photogates in gate mode along the track and record the distance x between gates.
(3) Release the cart fro
Conservation of Momentum Lab
Step 1 - Leveling Track
Place one bumper and one flag on each cart. Level the track by placing a cart in the middle of the track
with the air runn
Projectile Motion Lab
Part A: Launching a Projectile Horizontally
(1) Position the projectile launcher so that it launches the ball horizontally.
(2) Record the height of where the ball leaves the launcher.
(3) Push the ball all the way into the back (3 c
Archimedes Principle Lab
The buoyant force on an object always equals the weight of the fluid displaced.
We know that the buoyant force is: FBuoyant fluid gVsubmerged
The fluid that is displaced has a volume equal to the volume of the part of the object t
Newtons 2nd Law Lab
(1) Attach the hook and flag to the cart and measure the mass of the cart/hook/flag system using the
electronic scale. Measure the length of the flag.
Mass of cart/hook/flag (Mcart/hook/flag)
Mass of hanger (Mhang
Circular Motion Lab
The centripetal force acting
the rotating mass is given
4 2 MR
M = mass of the rotating
R = radius of orbit
T = period of orbit
(1) Clamp the base of the apparatus to the table so that it cannot slide a
Free Fall Lab
(1) Place the steel ball on the drop box. Set the timer to Time: Two Gates mode.
(2) Measure the distance between the bottom of the ball and the plate and record in table
(3) Release the ball using the timer switch and
Hookes Law Lab
In this lab, we will try to determine the spring constant (k) of a given spring using Hookes Law and the
period of a pendulum.
F k (d L) kd kL
where d = full length of spring at any given time
where L = initial length of the spring

A Particle is a Particle No Matter How Small
A proton charge is a stable subatomic particle occurring in all atomic nuclei. The charge
of a proton is +1 e, which is equal in magnitude to the electron charge, -1 e. This results in zero
net charge within at
Questions for Class Friday:
1. Can a black hole disappear?
1. Hawking: As particles escape from a black hole the hole will lose mass, and
shrink.This will increase the rate of emission of particles. Eventually, the black
hole will lose all its mass, and d
