You can't directly measure the force due to gravity with a single piece of equipment. Instead, you measure acceleration due to gravity using a device called a gravity meter or gravimeter.

Here's why:

* Force due to gravity is calculated using the formula: F = m * g, where:

* F is the force due to gravity

* m is the mass of the object

* g is the acceleration due to gravity

* Acceleration due to gravity is a constant value, approximately 9.8 m/s² near the Earth's surface. This means the force of gravity changes depending on the mass of the object.

So, while a gravimeter measures acceleration due to gravity, you would then need to know the mass of an object to calculate the force of gravity acting on it.

Here are some types of gravimeters:

* Absolute gravimeters: These directly measure the acceleration due to gravity using precise timing of a free-falling object.

* Relative gravimeters: These compare the gravitational acceleration at different locations to a reference point.
