Metric and Density
the metric system and density
| Term | Definition |
|---|---|
| Matter | anything that has mass and takes up space |
| Volume | the amount of space an object takes up -milliliters and liters(liquid) -cubic centimeters(solid) |
| Graduated Cylinder | tool used to measure the liquid volume when accuracy is important |
| Meniscus | the curve at the surface of a liquid |
| Mass | the amount of matter in an object -same no matter where in the universe -only way to change mass is to change the amount of matter in an object -measured by using a balance -kilograms or grams |
| Weight | measure of gravitational force exerted on an object -varies depending on where the object is in relation to Earth -measured with spring scale and newtons |
| Inertia | the tendency of an object to resist a change in motion |
| Density | a way to measure how tightly packed an object is d=m/v |
| Axis | x-axis is independent variable and time y-axis is dependent variable |
| SI | international system of units based on 10 |
| Density doesn't change | if the object is double or split in half, the density stills stay the same |
| Temperature VS Density (indirect relationship) | when the temperature rises, the density will decrease |
| Pressure VS Density (direct relationship) | when pressure increases on an object the density increases |
| Pressure | the amount of force exerted on a given surface |
| Temperature | a measure of how fast the particles in an object are moving |
| Decrease the size of an object and the mass stays the same... | density changes |
| Buoyancy | the tendency of an object to float or sink |
