2309: Module 1: General Fundamentals Quizzes
Which system uses the force of gravity to define mass? -British System -System International -both use the force of gravity
British System Feedback: The British System uses the force of gravity as a basis for the pound which is the unit of measure for mass or weight.Objective: Define the British System and System International.Reference: Module 1, Section 2, Screen 9
Which of the following is a unit of measure for a fundamental quantity? -Newton -kilogram -m/s -kg-m/s
kilogram Feedback: The kilogram, meter, and second are units of measure for fundamental quantities.Objective: Differentiate between fundamental and derived quantities. Reference: Module 1, Section 2, Screen 8
What is the velocity of an object if it travels 50 meters in 5 seconds? -25 m/s -250 m/s -10 m/s
10 m/s Feedback: To find velocity, we divide the distance by the time.Objective: Accurately use general physics formulas.Reference: Module 1, Section 2, Screen 12
What is the power consumed if 500 J of work is done in 4 seconds? -2,000 W -125 W -50 W
125 W Feedback: Objective: Accurately use general physics formulas. Reference: Module 1, Section 2, Screen 15
What is the force necessary to move a 100 kg object at a rate of 3 meters/second? -33N -300N -30N
300N Feedback: To find force, we multiply the mass times the acceleration.Objective: Accurately use general physics formulas. Reference: Module 1, Section 2, Screen 13
What is the work done if a force of 300 N is applied over a distance of 15 meters? -4,500J -3,000J -1,500J
4,500J Feedback: To find work, we multiply the force applied times the distance.Objective: Accurately use general physics formulas. Reference: Module 1, Section 2, Screen 15
Which of the following is solely a property of mass? -Time -Inertia -Velocity -Energy
Inertia Feedback: Inertia is solely a property of mass. All objects with mass have inertia.Objective: Explain matter, energy, and inertia, and give examples.Reference: Module 1, Section 2, Screen 17
All of the following are derived quantities except: -Velocity -Momentum -Force -Mass
Mass Feedback: Mass is a fundamental quantity and used to calculate some of the derived quantities such as force and momentum.Objective: Differentiate between fundamental and derived quantities.References: Module 1, Section 2, Screens 5 and 6
Which of the following is expressed in kg-m/s? -Velocity -Acceleration -Force -Momentum
Momentum Feedback: Momentum is measured in kg-m/s. Velocity is measured in m/s, acceleration in m/s², and force in N.Objective: Correctly use general units of measure.Reference: Module 1, Section 2, Screen 14
A unit of measure is a value agreed upon by a society to give meaning to a quantity. -True -False
True Feedback: Units of measure are important means of communication to give understanding, value, and meaning to quantities. Imagine the difficulty of communicating distance without an accepted unit of measure!Objective: Explain the concept of measure.Reference: Module 1, Section 2, Screen 3
