  1. Warm up and summarizing questions will be graded weekly- please write full question and answer for each day. If you miss a day please see a peer or myself after class to make up. September 14-18 Warm Ups & Summarizers Physical Science

  2. Monday September 14, 2015 SPS8. Students will determine relationships among force, mass, and motion. B-dEssential Question: How are mass and weight affected by gravitational force? Warm Up • Pat measures a small rubber ball and then makes three other balls of the same diameter from lead, foam, and wood. • Which ball has the greatest inertia? • A the rubber ball • B the lead ball • C the foam ball

  3. Monday September 14, 2015 SPS8. Students will determine relationships among force, mass, and motion. B-dEssential Question: How are mass and weight affected by gravitational force? SUMMARY - Given mass and acceleration how do you calculate force? Don’t forget to include units.

  4. Tuesday September 15, 2015 SPS8. Students will determine relationships among force, mass, and motion. B-dEssential Question: How is gravitational force manipulated? WARM UP • An airplane in level flight is acted on by four basic forces. Drag is air resistance, lift is the upward force provided by the wings, thrust is the force provided by the airplane’s engines, and weight is the downward force of gravity acting on the airplane. In level flight at constant speed, which pair of forces must be equal? • A lift and drag • B drag and weight • C lift and weight • D thrust and lift

  5. Tuesday September 15, 2015 SPS8. Students will determine relationships among force, mass, and motion. B-dEssential Question: How is gravitational force manipulated? SUMMARY • Mike wants to determine the weights of some small stones. He places each of them on a scale that measures the mass of each stone. Mike’s final results should be reported in which metric unit? • A grams/cm3 • B kilograms • C liters • D Newton’s

  6. Wednesday September 16, 2015 SPS8. Students will determine relationships among force, mass, and motion. B-dEssential Question: How are objects affected by gravitational force (Fg)? Warm Up Kahoot

  7. Wednesday September 16, 2015 SPS8. Students will determine relationships among force, mass, and motion. B-dEssential Question: How are objects affected by gravitational force (Fg)? SUMMARY • What is the weight on Earth of a girl with a mass of 30 kg? The acceleration due to gravity (g) on Earth is 9.8m/s2.

  8. Thursday September 17, 2015 SPS8. Students will determine relationships among force, mass, and motion. B-dEssential Question: How does distance affect gravitational force? Warm Up As the mass of an object increases, acceleration __________
