Q: A: ### Quick Answer

Mass and weight are closely related because mass affects the weight of an object experiencing the effects of gravity. Weight is the measure of the force of gravity on an object's mass, while mass is the measure of how much matter there is in an object.

Know MoreAn object's weight is calculated as the mass of an object in kilograms multiplied by the acceleration of gravity exerted in meters per second squared. The resulting number is expressed in newtons, named for Newton's second law of motion. An object's mass is determined by comparing it to an object with a known mass on a balance. An object with a mass of 1 kilogram would weigh 9.8 newtons on Earth, yet it would weigh essentially nothing in space while still having a mass of 1 kilogram.

## What is the formula for tension in physics?

A:

Full Answer >**In physics, the tension on a suspended object said to be equal to the weight of the object plus or minus the mass of the object times the acceleration acting on it.**In other words, this is the weight of the object plus or minus the force on it, depending on the direction in which the force is acting.Filed Under: - Q:
## How do you read a triple-beam balance?

A:To get the mass of an object using a triple-beam balance, sum up the notch readings of the rear beam weight, middle beam weight and front beam weight. Each notch on the middle beam, rear beam and front beam represents 100-gram, 10-gram and 1-gram weight increments, respectively.

## How do you calculate density?

A:

Full Answer >**Density of any object is calculated by dividing the object's mass by its volume.**Density is determined by the concentration of molecules in an object, so objects with a heavy mass in relation to a smaller volume have a higher density than objects with a lower concentration of molecules over a relatively large volume.Filed Under: - Q:
## Is momentum a vector quantity?

A:

Full Answer >**Momentum is a vector quantity as it is the product of mass and velocity of an object.**Mass is a scalar quantity but velocity is vector. In physics, the symbol for momentum is P, and its units are kilogram meters per second and gram centimeters per second.Filed Under:
