Frequently used equations in physics. Appropriate for secondary school students and higher. Mostly algebra based, some trig, some calculus, some fancy calculus.

Q is the electric charge, measured in coulombs [C]. i (t) is the momentary current, measured in amperes [A]. t is the time period, measured in seconds [s]. Electric charge generates electric …

Electric charge (symbol q, sometimes Q) is a physical property of matter that causes it to experience a force when placed in an electromagnetic field. Electric charge can be positive or …

The quantitative relationship between heat transfer and temperature change contains all three factors: (14.2.1) Q = m c Δ T, where Q is the symbol for heat transfer, m is the mass of the …

heat energy = (mass of substance) (specific heat) (change in temperature) Q = mc∆T Q = heat energy (Joules, J) m = mass of a substance (kg) c = specific heat (units J/kg∙K) ∆ is a symbol …

Jul 23, 2025 · In this article, we will cover all important formulas related to physics ranging from mechanics to electromagnetism as well as thermodynamics and quantum mechanics.

Formula for Heat Capacity The heat Capacity formula is expressed as the product of mass, specific heat, and change in the temperature which is mathematically given as:

Jul 11, 2025 · This article provides a focused exploration of the most common meanings of ‘q’ in physics, particularly within the realms of electromagnetism, thermodynamics, and nuclear …

The electric field strength (E) is defined as the amount of force exerted upon a test charge per unit of charge on the test charge (q). That is, E = F / q.

The majority of the thermodynamics problems you solve will revolve around the variable Q, but what is Q in thermodynamics? Q represents the amount of heat released or absorbed in a …
