To calculate the density of a substance what two properties do you need to know?

mass volume weight none of the above

density = mass/volume. so you need to know the mass and the volume.

To calculate the density of a substance we need mass and volume

Density is a physical quantity that compares the amount of matter an object has to the space that it occupies which is called its volume. An object with more matter in a certain volume has high density. Density is found by dividing the mass of an object by its volume.

Mathematically we can write as

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
