1. What's the Matter?

2. Everything Is the Matter! matter -everything is made of matter, which is anything that has volume and mass volume -volume is the amount of space occupied (taken up) by an object mass -mass is the amount of matter that an object is made of (how much of it there is) SOLID LIQUID GAS Matter exists in 3 common states

3. Turn up the Volume -all 3 states of matter have volume -liquid volume can be measured with a graduated cylinder and is commonly expressed in mililiters (mL) or liters (L) -solid shapes vary, but all exist in 3 dimensions, so the measures of those 3 dimensions are multiplied to find their volume, which is expressed in cubic units: cubic meters, cubic centimeters, cubic milimeters, etc. -to know the volume of a gas, you need to find the volume of the container it is in, so use the same process as for solid shapes

4. Mass appeal -generally speaking, a very large object has more mass than a very small object, however, size is not always a good indicator of mass -mass is measured in kilograms (kg), grams (g),or miligrams (mg) weight -mass is often confused with weight -weight is a measure of the gravitational force exerted on an object, while mass, again, is how much matter the object is made of -so, weight measures the effect of gravity on an object's mass -because weight measures a force, it must be newton expressed in the unit of force, called the newton (N) (N), one newton is approximately equal to the weight of a 100g mass on Earth.

5. Understanding the Gravity of the situation gravity -gravity is a force of attraction between objects with relation to mass -it causes objects to exert a pull on other objects -the amount of pull,or attraction, depends on the mass of the objects, and the distance between them Large objects that are close together have a large gravitational force. Small objects that are close together have a smaller gravitational force than larger objects that are close together. Increased distance reduces gravitational force, so even large objects have less gravitaional force if they are far apart.

6. Inner what? inertia -inertia is the tendency of all objects to resist any change in motion -an object at rest (not moving) will stay at rest unless something causes it to move -an object in motion will remain in motion at the same speed and in the same direction unless something causes it to change speed or direction -mass is a measure of inertia -this is because an object with a large mass is more difficult to start and stop than one with a small mass
