CSEC® Physics Revision Course

These flashcards are designed to aid students in reviewing essential vocabulary and concepts for CSEC Physics.

What does Archimedes' principle state?

A body submerged in a fluid experiences an upthrust equal to the weight of the fluid displaced.

Define potential difference.

The energy used or work done in transferring unit charge between two points.

What is the formula for specific heat capacity?

c = Q / (m * ΔT), where c is specific heat capacity, Q is heat energy, m is mass, and ΔT is temperature change.

What is Newton's first law of motion?

A body continues in its state of rest or uniform motion unless acted upon by an external force.

How does temperature affect the rate of evaporation of a liquid?

As temperature increases, the molecules move faster, increasing the chance of overcoming intermolecular forces and escaping as gas.

State the formula for Boyle's law.

P1V1 = P2V2, where P is pressure and V is volume for a fixed mass of gas at constant temperature.

What is the principle behind the operation of a transformer?

A transformer increases or decreases an alternating voltage via electromagnetic induction between coils.

What is the difference between mass number and atomic number?

Mass number (A) is the total number of protons and neutrons in an atom, while atomic number (Z) is the number of protons.

Define frequency.

The number of complete cycles of a wave that pass a given point in one second, measured in hertz (Hz).

What is the unit of electrical resistance?

Ohm (Ω), defined as the resistance when a voltage of one volt produces a current of one ampere.
