# Mass and Weight

## 06 Feb Mass and Weight

Physics is one of the most important branches of Science and it is also essential to learn Physics for a student who wants to pursue their career in Engineering, Medical, Research, and other fields. Physics provides us with answers about a lot of things, but to students, this subject sounds like an array of hard to understand formulas and theories.

At the classes of A level physics tuition, O level physics tuition, JC physics tuition offered by Miracle Learning Centre, the best teachers of Singapore will break down the complex topics of Physics into simplest forms.

Physics tuition classes in Miracle Learning Centre is easy to understand and help you to improve in your grades. If you do not understand physics, you must definitely attend the physics tuition class at Miracle Learning Centre. Let us learn about Mass and Weight in this physics tuition lesson.

Mass is a measure of the amount of matter or substance in a body. It is the property of a body that does not change due to its location, shape and speed. The mass of a body depends on the number and composition of atoms and molecules that make up the body.

Weight is the force with which gravity attracts an object. An object will weigh more on earth than on the moon because earth’s gravity is greater than moon’s. This also depends on how far or close to the attracting body the object is located.

Mass is constant no matter what the location is. Mass is a scalar quantity. Mass is measured in kilogram. Mass is measured using beam balance. Weight depends on acceleration due to gravity at the location. Weight is a vector quantity. Weight is measured in newtons. Weight is measured using spring balance.

The student at Miracle Learning Centre asked, ” What is gravitational field?”

The physics tuition teacher at Miracle Learning Centre replied,” Gravitational field is a region in which an object experiences a force of attraction due to the presence of the attracting body. Any object placed on Earth experiences a force pulling it towards the centre of Earth. The Earth’s gravitational field is located all around it, extending to infinity. The gravitational force is therefore the strongest on the surface of the Earth and gets weaker as we move farther away from it.”
