  1. Chapter 2 Review

  2. My clicker is working • Yes • no

  3. Weight is… • How much matter is in something • A measure of the force of gravity’s pull • The same as weight • A value that does not change with location • I don’t know

  4. Density is • The volume per unit mass • The mass per unit volume • The weight of an object • How much matter is in an object • IDK

  5. Gravity is affected by two things • Mass and distance between objects • Mass and weight • Location and mass • Density and volume • IDK

  6. Metric weight is measured in • Kilograms • Grams • Centimeters cubed • Newtons • IDK

  7. The resistance of an object to change its motion is called • Inertia • Mass • Density • Gravity • IDK

  8. The equation to find metric weight is • Mass = weight x ag • N = kg/ag • Weight = mass x ag • D = m/v

  9. N = kg x ag solve for kg • kg = N x ag • kg = ag/N • kg = N/ag • IDK

  10. The value for G on Earth is • 9.81 N • 9.81 m/s • 9.81 kg • 9.81 m/s2

  11. If you have as mass of 50kg what is your weight • 490.5 kg • 490.5 N • 5.09 N • 5.09 kg • IDK

  12. If a cube has a side length of 4cm and a mass of 20 kg what is its density? • 5 kg/cm3 • .31 kg/cm3 • 80 kg/cm3 • 3.2 kg/cm3 • IDK

  13. I can change an objects density by • I can not change density • Cutting it in half • Adding more matter of the same type to it • Changing its temperature • IDK

  14. Which is more dense, a ton of ice or a small rock • There is not enough information • The ton of ice • The rock • They are equal • IDK

  15. What is the relationship between mass and inertia • More mass more inertia • Less mass more inertia • More information is needed • They are not related • IDK

  16. What has the least inertia? • A parked 865 kg car • A thrown 4 kg baseball at 92 mph • A 49 kg child on a bike riding at 2 mph • A 89 kg person running at 5 mph • IDK
