1. Measuring Weight

2. MASS AND WEIGHT ►M►Mass and Weight ARE NOT the same thing!

3. MASS – Expressed in grams or kilograms – Does not change no matter where you are – Measured using a triple beam balance or an electronic balance – Amount of matter in an object

4. INERTIA Inertia is the tendency of an object to resist a change in motion. (We will revisit this later in the year.) Mass is a measure of inertia. The more mass something has, the greater the inertia.

5. Weight Amount of the gravitational force exerted on an object. depends on mass more mass = more weight SI Units Newtons (N) Tool Spring Scale
