what is mass?

Mass is property of matter than make celeration. It can be converted to energy.

You are asking a physi question, not a math question.

An express bus and a local bus starty out at 1st Street together. The express bus stops every 15 blocks. The local bus stops every 4 blocks. How many blocks will it be before there is a bus stop where both buses stop?

Mass is a fundamental property of matter that measures the amount of matter in an object. It is a scalar quantity, meaning it has magnitude but no direction. The standard unit of mass in the International System of Units (SI) is the kilogram (kg).

To understand what mass is, we need to differentiate it from weight. Mass remains the same regardless of the location, but weight depends on the gravitational pull acting on the object. For example, if you were to take an object from Earth to the Moon, its mass would remain the same, but its weight would be less on the Moon due to its weaker gravity.

Now, let's discuss how to measure mass. The most common method is by using a balance, such as a digital scale, which determines the amount of force required to counteract the gravitational pull on an object. This force is proportional to the mass of the object. By comparing it with a known mass, we can determine the unknown mass of an object.

Another way to measure mass is by using Newton's second law of motion. This law states that the force acting on an object is equal to its mass multiplied by its acceleration. By applying a known force to an object and measuring its resulting acceleration, we can calculate its mass by rearranging the equation.

In summary, mass is a measure of the amount of matter in an object. It can be measured using a balance or by applying a known force and observing the resulting acceleration using Newton's second law of motion.
