Physic

Micrometer Screw Gauge

An instrument used to measure small lengths accurately (to 0.01 mm or 0.001 cm).

Total Thickness Measurement

The total thickness is calculated by adding the sleeve reading and thimble reading from a micrometer.

Displacement Method

A technique for finding the volume of an irregular object by measuring the change in water level in a measuring cylinder when the object is submerged.

Base Quantities

Fundamental quantities that include length, mass, and time.

Derived Quantities

Quantities that are derived from base quantities, such as speed (L/T) and force (M⋅L/T²).

Dimension Analysis

A method used to check if an equation is physically correct by analyzing the dimensions of the physical quantities involved.

Greenhouse Gases

Gases such as CO₂ and CH₄ that trap heat in the atmosphere and contribute to an increase in the Earth's temperature.

Ways to Reduce Global Warming

Methods such as reducing fossil fuel use, planting trees, using renewable energy, and conserving energy.

Measuring Cylinder

A graduated cylinder used for measuring the volume of liquids, particularly in the displacement method.

Vf−Vi

The formula for calculating the volume of a stone using the displacement method, where Vf is the final water level and Vi is the initial water level.
