MASS VS WEIGHT: NAME:WEIGHT THROUGHOUT THE UNIVERSE DATE:

BLOCK:

Use your mass to determine your weight in other places in the universe.

1. First, change your weight in lbs to your mass in kg.

__________________ x 0.4536 = __________________ kg

2. Fill in your mass for each place throughout the universe.3. Multiply you mass by the gravity in each place to find out your weight.

1. Where do

you weigh the most? _________________________________2. Where do you weigh the least? _________________________________

BALANCED FORCES AND UNBALANCED FORCES Name:Date:Block:

Circle the BEST answer:

1. The forces shown above are PUSHING / PULLING forces.2. The forces shown above are WORKING TOGETHER / OPPOSITE FORCES.3. The forces are EQUAL / NOT EQUAL.4. The forces are BALANCED / UNBALANCED.5. The forces DO / DO NOT balance each other.6. The resultant force is 1000 N TO THE RIGHT / 1000 N TO THE LEFT/

ZERO.7. There IS / IS NO motion.

1. The forces shown above are PUSHING / PULLING forces.2. The forces shown above are WORKING TOGETHER / OPPOSITE FORCES.3. The forces are EQUAL / NOT EQUAL.4. The forces are BALANCED / UNBALANCED.5. The stronger force is pulling to the RIGHT / LEFT.6. The weaker force is pulling to the RIGHT / LEFT.7. The resultant force is 100 N TO THE RIGHT / 100 N TO THE LEFT / ZERO.8. Motion is to the RIGHT / LEFT.
