All objects have a force that attracts them towards each other. This force is called gravity.

This website provides good information and examples of gravity, mass and weight.

Weight is a force caused by gravity. Because it is a force, it is also measured in Newtons (N). It is the gravitational force between the object and the Earth.

Weight is just another word for the force of gravity. Weight is a force that acts at all times on all objects near Earth.

Every object is made up of matter (Matter is anything you can touch physically). The more matter an object has, the bigger it is, and the more mass it has.

Mass is a measurement of how much matter is in an object. Mass is a combination of the total number of atoms, the density of the atoms, and the type of atoms in an object.
