What is the formula for calculating density?

• Density = Volume / Mass

• Density = Weight / Volume

• Density = Mass / Volume

• Density = Force / Area

What is the difference between mass and weight?

• Mass is the force exerted on an object due to gravity, while weight is the amount of matter in an object

• Mass and weight are the same thing

• Mass is measured in pounds, while weight is measured in kilograms

• Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity.

What is the law of universal gravitation?

• Every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

• The law that explains the movement of planets around the sun

• The law that states all objects are attracted to the Earth

• The law that describes the force of gravity on an object's weight

What is the difference between an element and a compound?

• An element is a pure substance made up of only one type of atom, while a compound is a substance made up of two or more different types of atoms chemically bonded together.

• An element is made up of two or more different types of atoms, while a compound is made up of only one type of atom

• An element is a mixture of different substances, while a compound is a pure substance

• An element and a compound are the same thing
