Question
Use the table to answer questions 27-29. An investigation is conducted and the following results are recorded. Force Needed to Lift a Brick 20 cm Force Needed to Lift a Brick 20 cm Using a Ramp Trial Mass of a Brick 1 487 g 20 N 9N 487 g 21 N 10 N 3 487 g 20 N 10 N 4 487 g 19 N 9N 27 Which set of lab equipment is most likely used to conduct this investigation? A Spring scale, balance, lever B Spring scale, incline plane, balance C Balance, stopwatch, safety goggles D Balance, lever, safety goggles 28 Which of the following hypotheses is most likely being tested in this investigation? F If you lift the brick with a spring scale, then the brick will have less mass. G If you roll the brick up the ramp, then more force is needed to move the brick. H If you slide the brick up a ramp, then less force is needed to move the brick. J If you increase the mass of the brick, then more force is needed to lift the brick. 29 What is the best conclusion that can be made based on the data from the investigation? A A ramp allows us to use less force when doing work. B A ramp allows us to use more force when doing work. C Spring scales are not accurate tools of measurement. Spring scales should always be used to lift the brick. Gateways to Science, STAAR Edition, Grade 7 Page 12 of 13
