Step-by-step explanation:
When it comes to abbreviating terms such as "laws of gravity" in your notes, clarity is key. The best abbreviation is one that will allow you to quickly identify the term when you're reviewing. Option d) l of 's grav. stands for "laws of gravity" in a recognizable way and is more distinctive than the other options provided. It is concise and will help you identify the concept effectively while studying.
Newton's law of universal gravitation and the gravitational constant are fundamental in understanding gravitational interactions. Newton's law can be summarized mathematically by the equation F = Gm1m2/r², which states that the force (F) between two masses (m1 and m2) is proportional to the product of their masses and inversely proportional to the square of the distance (r) between them, with G being the gravitational constant.
