1. Define Mass –. 2. Define Weight –. 3. Describe what will happen (if anything) to mass and weight when you go to the moon. a. Why would this happen? 4. Find the weight of a 60 kg astronaut on earth. a. Find the weight of the same object on a planet where the gravitational attraction has been reduced to 1/10 of the earth’s pull. Show all work. 5.
Experiment. Collect a 20N spring balance and a set of 100 g masses. Predict the weight (force of gravity) on 100 g. Record this in the table. Test your answer and record the measured weight. Repeat for other masses until you can discover a relationship. Replace the 20 N spring balance with a 50 N spring balance and place 5 kg on the end.

Mass is a measure of the amount of matter in an object. Mass is not related to gravity. The mass of an object does not change when it is moved from one place to another. Mass is commonly measured in grams or kilograms. Weight is a measure of the gravitational force between two objects.
