F = mg
Definition
F = mg is the equation that represents the force of gravity acting on an object. It states that the force (F) exerted on an object is equal to its mass (m) multiplied by the acceleration due to gravity (g).
Analogy
Imagine you have a backpack filled with textbooks. The weight of the backpack can be represented by F = mg, where m is the mass of the textbooks and g is how strong gravity pulls them down. The heavier the textbooks or the stronger gravity, the greater force you feel pulling you down.
Related terms
Weight: Weight refers to the force experienced by an object due to gravity. It is calculated using W = mg, where W represents weight, m represents mass, and g represents acceleration due to gravity.
Acceleration due to Gravity: Acceleration due to gravity (g) is a constant value that represents how quickly objects accelerate towards Earth when falling freely under gravitational influence. On Earth's surface, it has an approximate value of 9.8 m/s².
Force: Force refers to a push or pull applied to an object resulting in its acceleration or deformation. It can be measured in Newtons (N).
