A triple beam balance is a device that measures the mass of an object by comparing it with a system of three counterweights. The advantage of using this system is it allows you to measure the weight of an object extremely precisely. You can measure the mass of an object by learning to ...
What is the mass of the object (to the closest tenth of a gram)? Remember to find the mass using a triple beam balance you must add the mass values of each of the three beams. Type your answer in the space provided below, then hit the submit button. The mass of the object is: P...
The measure of inertia of an object is known as the mass of that object. The mass of an object can be obtained by calculating the product of the volume and density of the object. The SI unit of mass is kilogram (Kg). Answer an...

The easiest way to find the mass of anything is to weigh it. You're actually measuring the force of gravity on the object, and technically, you should divide the weight by the acceleration due to gravity to get the mass. For most applications, though, weight and mass are essentially equiv...
A physicist explains why mass is both well-defined and also a bit complicated, especially as the masses get really minuscule.

A closed trajectory in a central field of force is significant because it allows us to determine the mass of an object without directly measuring it. This is useful in situations where the object's mass cannot be easily measured, such as in space. Additionally, the shape and size of ...
