Physics Laboratory Tools and Equipment

These flashcards cover common physics laboratory tools and equipment, their functions, and the specific physical quantities they measure as described in the lecture.

Science Laboratory

A place where scientific research and development are conducted and analyses performed.

Laboratory Equipment

Refers to the various tools and equipment used by scientists working in a laboratory.

Triple Beam Balance

A tool used to measure mass by balancing an object against three sliding weights on calibrated beams.

Spring Balance

An instrument that measures force or weight by the extension of a calibrated spring.

Set of Weights

Provides known standard masses for use with beam or platform balances when determining an unknown mass.

Digital Balance

A high-precision measuring instrument used for accurately measuring weight with a digital display and electronic sensors.

Meter Stick

A measuring tool used to measure distance in a straight line.

Cloth Tape Measure

A portable tool used to measure long, flexible distances such as rooms or fabric.

Retractable Tape Measure

A tool primarily used for measuring distances or dimensions in construction and carpentry.

Micrometer

A device used to measure extremely small thicknesses or diameters, typically featuring increments of $0.01\,mm$.

Vernier Caliper

A high-precision instrument used for measuring internal and external dimensions as well as the depths of objects.

Beaker

A container used to hold, mix, or heat liquids, providing rough volume estimates in units such as $cm^3$.

Erlenmeyer Flask

A conical container used to mix and store liquids; its shape is suitable for swirling contents without spilling.

Pipette

A tool used to measure and transfer a small, specific volume of liquid.

Stopwatch

A time-measuring device used for accurate time interval measurement between activation and deactivation.

Magnetic Compass

A navigational instrument used to determine direction through unknown territories.

Thermometer

An instrument used to measure body temperature or track changes in temperature; types include alcohol, mercury, and digital.

Ammeter

An instrument used to measure the electric current in a circuit in units of amperes ($A$).

Galvanometer

A device used to detect and measure small electric currents or to determine their magnitude.

Ohmmeter

A device used to measure the electrical resistance within a circuit.

Electroscope

An instrument used to detect the presence of an electric charge on an object.

Pliers

A tool used to grip, bend, or cut wires and other small components.

Screwdriver

A manual tool used for tightening or loosening screws.

Calorimeter

An apparatus used to measure the heat released or absorbed during a chemical or physical process.

Pulley

A simple machine that changes the direction of a force and can reduce the effort needed to lift objects.

Slinky Spring

A flexible spring used in physics to visualize and demonstrate wave behavior.

Alcohol Lamp

A small, portable, and smokeless heat source used for gentle heating tasks, sterilization, and combustion.

Tuning Fork

A metal tool that demonstrates resonance in sound waves by producing a steady sound when struck.

Prism

A triangular block of glass that bends or refracts light as it passes through.

Optical Mirrors

Tools used to study reflection laws, image formation, and focal length.

Optical Lens

A component used to focus or spread light rays in experiments concerning refraction, magnification, and optical instruments.

Magnet

A material that attracts other magnetic materials (such as iron) and produces a magnetic force that can attract or repel other magnets.
