PHYSICS INSTRUMENTS

Ticker Tape Timer devices that use a long roll of ticker tape to countintervals. These intervals are decided by the vibration ofthe timer itself, which usually vibrates at around 50 hertz.

As the timer vibrates, it makes marks on the ticker tape,typically a series of dots that can then be read as aninterval of time.

Time of flight accessory

The Time-of-Flight Accessory is designed primarily forfree fall or projectile experiments. When a projectile islaunched or object dropped, a photogate starts the timingof one of PASCO's timing systems. When the object hitsthe plate of the Time-of-Flight Accessory and makes anoise, a signal is sent to the interface to stop the timer.The signal is identical to the signal sent by a blockedphotogate.

Linear Expansion Apparatus device makes studying the expansion of metals simpleand instantly visible to the student. A metal rod is insertedinto the steam chamber and steam is applied. Expansionof the rod is immediately registered by the dial indicatorthat is mounted on one end. The heat jacket has threeinlet tubes for water intake, outlet and thermometerinsertion. Unit includes four metal rods 6mm x 60cm ofaluminum, steel, copper, and brass. A steam source is notprovided. The unit measures 8 cm x 10 cm x 70cm.Instructions included.

Calorimeter experimental apparatus that measures the energy ofparticles. Most particles enter the calorimeter and initiatea particle shower and the particles' energy is deposited inthe calorimeter, collected, and measured.calorimeters aresegmented transversely to provide information about thedirection of the particle or particles, as well as the energydeposited, and longitudinal segmentation can provideinformation about the identity of the particle based on theshape of the shower as it develops. Calorimetry design is

an active area of research in particle physics.Thermometer device that measures temperature or temperaturegradient using a variety of different principles.[1] Athermometer has two important elements: thetemperature sensor (e.g. the bulb on a mercurythermometer) in which some physical change occurs withtemperature, plus some means of converting this physicalchange into a numerical value (e.g. the scale on amercury thermometer).

device that uses a heat source to boil liquid water andconvert it into its vapor phase, referred to as steam. Theheat may be derived from the combustion of a fuel suchas coal, petroleum fuel oil, natural gas, municipal waste orbiomass, a nuclear fission reactor and other sources.

used by means of turning the screw through the bottom of

the frame until the desired state of pressure or release isreached. In the case that the clamp is being tightened,this is when the objects being secured are satisfactorilysecured between the flat end of the screw and the flat endof the frame. If the clamp is being loosened, this is when asufficient amount of force is released to allow the securedobjects to be moved.

A stove is a heat-producing device.

Motion Sensor a device that detects moving objects, particularlypeople. A motion detector is often integrated as acomponent of a system that automatically performsa task or alerts a user of motion in an area

Photogate Head has a narrow infrared beam and a fast fall time thatprovide very accurate signals fortiming.

Picket Fence a variety of fence that has been used mostly fordomestic boundaries

illustrates the idea that motion in differentdimensions is absolutely independent. A goodlauncher not only illustrates this non-intuitive idea,but it can be used to describe the exact motion ofthe projectile as well

Super Pulley wheel on an axle that is designed to supportmovement of a cable or belt along its circumference

Meter Stick a unit of measurement used for measuringobjects that are longer than 12 in. A meterstick usually measures things off incentimeters and millimeters. A metermeasures out to about three feet.

Micrometer Caliper a measurement device for finding very exactmeasurements of an item;

it measures things to a very tight scale andoften features a built-in readout of the size ofthe measured object

Vernier Calipera measuring device from a compass to intenseinstruments such as the vernier caliper actingas an advanced ruler. The vernier caliper usesvernier scale to measure more precisely. This

instrument provides different methods ofmeasuring including ways to measure externalor internal dimensions as well as finding depthmeasurements. In fact the depth measurementmethod of usinga movable and slide-able probe is so slenderthat it is able to retrieve data in deep canals

1. Angle Indicator is an accessory used for measuring angles from 0 to 90 in two directions. There are

four different methods of using the Angle Indicator: hand-held, by tying a string to each side of the device

attached to a PASCO Dynamics Cart, by sliding the device into the slots on the top of the cart. It is

necessary to adjust the thumbscrew and square nut as far up as possible on the Angle Indicator.

slipped over the platform on the PASCO CI-6538 Rotary Motion Sensor.

2. Dynamic Cart

These carts are tough enough to withstand the worst that students can dish out.

More importantly, their axles are aligned to insure that they roll a true line without deviation,

minimizing drag and making for accurate data.

They give superior data for all quantitative kinematics experiments. Each cart weighs about

1.5kg and rides on three steel ball bearing wheels. The bodies at 31 x 9cm will accept standard bricks as

weights.

The cart bed is covered with a non slip rubber pad and the ends rise above the bed to contain a

brick or any other masses.Each cart also carries a clip at one end to attach a timing tape. One cart features a rubber

tipped, trigger released, piston with two different thrust levels. Each cart comes with twelve 3 3/4?

rubber loops.

The cart with exploding piston also comes with a roll of adhesive tape.

We offer the carts as a set or individually. Instructions included.

3. Dynamic track

PURPOSE: To show Newton's second law.

DESCRIPTION: A dynamic cart rests at one end of a long, level dynamic track. Load the spring

mechanism on the dynamic cart by pushing it in and upward. Use a mallet to carefully release the hair

trigger and allow the spring to push the cart the length of the track. Now reset the spring and add two

masses to triple the mass of the cart. Again, release the hair trigger with the mallet and show that the

cart moves some shorter distance. This is similar to the air track glider but there is some small amount

of desirable friction and no noise because there is no air blower.

EQUIPMENT: long dynamic track, spring loaded dynamic cart, two masses.

SETUP NOTES: Be sure that the track is leveled.

4. Force sensor

The force sensor is a physics lab apparatus measuring the tensile force and pressure force. The sensor is

characterized in measuring interaction force between measured objects under movement state, such asNewton's Third Law, overweight and weight loss, sliding friction, force decomposition synthesis and

other experiments.

5. Force table

A force board (or force table) is a common physics lab apparatus that has three (or more) chains or

cables attached to a center ring. The chains or cables exert forces upon the center ring in three different

directions. Typically the experimenter adjusts the direction of the three forces, makes measurements of

the amount of force in each direction, and determines the vector sum of three forces. Forces

perpendicular to the plane of the force board are typically ignored in the analysis.

"The Force Table" is a simple tool for demonstrating Newtons First Law and the vector nature of

forces. This tool is based on the principle of equilibrium. An object is said to be in equilibrium when

there is no net force acting on it. An object with no net force acting on it has no acceleration. By using

simple weights, pulleys and strings placed around a circular table, several forces can be applied to an

object located in the center of the table in such a way that the forces exactly cancel each other, leaving

the object in equilibrium. (The object will appear to be at rest.) We will use the force table and Newtons

First Law to study the components of the force vector.
