How to Calculate the Force of Gravity on an Object?

What is the formula to calculate the force of gravity on an object?

Is it F = mg or F = ma?

Answer:

The correct formula to calculate the force of gravity on an object is F = mg.

When determining the force of gravity acting on an object, the formula F = mg is used. In this formula, F represents the force of gravity, m is the mass of the object, and g is the acceleration due to gravity.

Acceleration due to gravity, denoted as g, is a constant value on Earth and is approximately 9.81 m/s². This means that for every kilogram of mass, the force of gravity pulling it towards Earth is 9.81 newtons.

Therefore, to calculate the force of gravity on an object, you simply multiply the mass of the object by the acceleration due to gravity. This formula is valid for objects near the surface of the Earth.
