Physics Basics for Beginners IGCSE , IB , AMERICAN

Explore dimensional analysis by expressing physical quantities with M, L, and T, distinguishing fundamental from derived quantities, and learning to write dimensional formulas for volume and velocity and derive units.

Learn to express large and small numbers in standard form using SI prefixes, and convert units with a division method, including 1000 = 10^3 and 0.05 = 5 × 10^-2.

Solve problems on measuring tools, dimensional analysis, and SI units by distinguishing fundamental and derived quantities, with examples of velocity as a vector and using vernier calipers and micrometers.

Explore standard formula and scientific notation to express numbers as powers of ten. Use division of prefixes to convert units, from milli to micro and kilometer to centimeter.

Explore the difference between scalar quantity and vector quantity, learn how to differentiate them, and review examples to reinforce understanding of basic physics concepts.

Define distance as the actual length traveled and displacement as the straight-line vector with magnitude and direction. Illustrate how distance sums along paths while displacement is the shortest start-to-end line.

Distinguish fundamental quantities such as mass, length, and time from derived ones, and solve scalar and vector questions using displacement, distance, and direction.
