In the context of the movie "Mass," the term "mass" refers to a gathering or assembly of people, often for a religious service, but it can also symbolize the collective emotional weight and impact of a tragic event. The film explores themes of grief, forgiveness, and the complexity of human relationships, particularly in the aftermath of a violent incident that affects two families. The term underscores the shared burden of loss and the process of confronting pain and seeking understanding among individuals.

In a Catholic church, "Mass" refers to the central act of worship, where the Eucharist (Holy Communion) is celebrated. It involves several key components, including readings from the Bible, prayers, the consecration of bread and wine, and the reception of Communion by the congregation. The Mass is a ritual that commemorates the Last Supper of Jesus Christ and emphasizes themes of sacrifice, community, and spiritual nourishment. It is held regularly, typically on Sundays and holy days, and is considered a vital aspect of Catholic faith and practice.

In the context of the body, mass refers to the amount of matter contained within it, typically measured in kilograms or grams. It is a fundamental property that contributes to weight and is influenced by the composition of tissues, organs, and fluids. In biological terms, body mass can include muscle, fat, bone, and water. It is an important factor in assessing health, fitness, and metabolism. Body mass can be quantified using various methods, including body mass index (BMI), which relates weight to height for a general assessment of body composition.

In the context of matter, "mass" refers to the amount of substance contained in an object, which is a measure of its inertia and resistance to acceleration when a force is applied. Mass is typically measured in kilograms or grams and is a fundamental property of physical objects. It is distinct from weight, which is the force exerted on an object due to gravity. Mass remains constant regardless of location, while weight can vary based on gravitational pull. In physics, mass plays a crucial role in calculations involving motion, force, and energy.
