Final answer:
The 'Newton's Law Of Gravity' section best explains how to measure gravitational force on an object by using the formula F = mg, where m is the mass of the object and g is the acceleration due to gravity.
Step-by-step explanation:
The section that best explains how to measure the strength of the force between an object and the surface it stands upon is 'Newton's Law Of Gravity.' This section includes the relevant equations and concepts necessary to calculate the gravitational force. Specifically, Newton's universal law of gravitation provides a formula that can be used to calculate the force of gravity (F) on an object near Earth's surface by multiplying the object's mass (m) by the acceleration due to gravity (g), which is approximately 9.80 m/s². The formula derived from this law is F = mg, where m is the mass of the object, and g is the acceleration due to gravity.
To measure this force on Earth, the mass of the object (m) and the value of acceleration due to gravity (g) are used. Because the gravitational force is essentially weight, this calculation gives us the weight of the object as the measure of the force due to gravity on that object.
