一个可以用来测量力的工具。
A lever.
Gravity is typically measured using a tool known as a gravimeter or accelerometer. These devices detect the gravitational pull exerted by an object, such as the Earth, and can provide measurements of gravitational force.
A machine.
A spring is an object that returns to its original shape after being stretched and is measured in force meters. When a spring is stretched or compressed, it exerts a force proportional to the distance it is stretched, making it a common force measuring tool.
A force gauge is a tool that can measure the size of a force. It typically consists of a spring that deforms under the applied force and a scale that indicates the amount of force applied. Force gauges are commonly used in various applications such as material testing, quality control, and research.

The push or pull exerted on one object by another is simply a force and this is measured in Newtons. Using Newtons second law: Force = mass * acceleration, we can see that one Newton is the force required to move a one kilogram mass at a rate of one meter per second squared.

Depending on the size of the rock - if it is small enough it can be measured in a container with water the size can be judged by seeing how much water it displaces
The term for a tool that makes work easier by changing the size or direction of a force is a "lever." Levers are simple machines that involve a rigid bar or beam that pivots on a fulcrum to help in lifting or moving objects with less effort.
The unit of mass of a rock is typically measured in kilograms (kg) or grams (g). A common tool to measure the mass of a rock is a balance scale or a digital scale.
