Which variable represents force in physics equations?

In physics, the variable that represents force is commonly denoted by the letter F. This is grounded in Newton's Second Law of Motion, which states that force is equal to mass multiplied by acceleration (F = ma). The use of F as the symbol for force is a standardized convention in the field, making it universally recognized across various branches of physics and engineering.

The other options refer to different physical quantities. T typically represents tension, particularly in contexts involving ropes and pulleys. P is used for power, which is the rate at which work is done or energy is transferred. W is generally associated with work, which is defined as the transfer of energy through a force acting over a distance. Understanding these distinctions helps clarify why F is the appropriate choice for representing force in physics equations.
