Weight: Quiz

  
  

Question 1: In practical or everyday applications, weight means the same as ________ as that term is used in physics.
Classical mechanicsForceGeneral relativityMass

Question 2: For example, on the surface of the ________, gravity is only about one-sixth as strong as on the surface of the Earth.
Io (moon)Mercury (planet)Ganymede (moon)Moon

Question 3: For example, using ________, a mass of 1 kg experiences a weight force of 1 kg × 9.8 m/s2 = 9.8 newtons (note that the newton is equivalent to kg m/s2).
Metric systemInternational System of UnitsSystems of measurementConversion of units

Question 4: In ________, the pound can be either a unit of force or a unit of mass.
Imperial unitsUnited States customary unitsCanadian unitsEnglish units

Question 5:
Weight, Force and Friction are all:
Mass Force Physiology All accuracy disputes

Question 6: For example, the apparent weight of an object immersed in water is smaller than in air; this is due to ________, which opposes the gravitational force and therefore generates a smaller normal.
BuoyancyPhysicsFluid staticsSurface tension

Question 7: The use of "weight" for "mass" also persists in some scientific terminology – for example, the chemical terms "atomic weight", "molecular weight", and "formula weight", can still be found rather than the preferred "________" etc.
Avogadro constantOxygenMolar massAtomic mass

Question 8:
Weight, Body mass index and Thermal mass are all:
Force Physiology Mass All accuracy disputes

Question 9: [1] Near the surface of the ________, the acceleration due to gravity is approximately constant; this means that an object's weight near the surface of the Earth is roughly proportional to its mass.
SunEarthNatureMoon

Question 10: A spring scale or hydraulic or pneumatic scale measures local weight, the local ________ of gravity on the object (strictly apparent weight force).
EnergyPhysicsClassical mechanicsForce
