In science, mass is the amount of matter an object has. Newton's second law says that mass is the property of matter that determines the force required to impart a given acceleration to an object. More »

In science, speed is defined as the total distance traveled divided by the total time it took to travel that particular distance. Speed is dependent on the amount of time that it takes a person or object to move toward s... More »

In science, a solvent is the component of greatest amount in a solution. It is the component into which the solute dissolves. A solution is a mixture of two or more substances that occur as any phase of matter. More » Science Chemistry Solutions & Mixtures

Weight is a measurement of the force placed on an object by gravity, whereas mass is the amount of matter an object contains. Mass is commonly denoted using m or M, and weight is denoted with W. More »

The mass of an object is the amount of matter it contains while volume is the amount of space it takes up. Mass should not be confused with weight, which is the measure of the gravitational force on an object. More »

Mass is a measure of the amount of matter contained by an object, while weight is a measure of the gravitational pull on an object. As the gravitational force exerted by Earth is the constant upon which mass is calculate... More »

Anything that has mass and volume is called matter. There are four classical states of matter: solid, plasma, liquid and gas. Each type of matter has different properties. More »
