Mass And Weight Flashcards
What is the definition of mass?
Mass is the amount of matter in an object, measured in kilograms (kg).
What is the standard unit of weight?
The standard unit of weight is the newton (N).
True or False: Weight and mass are the same thing.
False.
What formula is used to calculate weight?
Weight (W) = Mass (m) × Gravitational Field Strength (g).
Fill in the blank: The gravitational field strength on Earth is approximately _____ N/kg.
9.81
What is the relationship between mass and weight?
Weight is directly proportional to mass; as mass increases, weight increases.
Multiple Choice: Which of the following is NOT a unit of mass? A) Kilogram B) Gram C) Newton D) Tonne
C) Newton
What does a balance measure?
A balance measures mass.
True or False: An object’s weight can change depending on its location in the universe.
True.
What is the mass of an object that weighs 30 N on Earth?
Mass = Weight / Gravitational Field Strength = 30 N / 9.81 N/kg ≈ 3.06 kg.
Multiple Choice: Which of the following is a correct statement? A) Mass is affected by gravity B) Weight is affected by gravity C) Both A and B
B) Weight is affected by gravity.
What is an example of a situation where weight changes but mass remains constant?
An object taken to the Moon will weigh less due to the Moon’s lower gravitational field strength, but its mass remains the same.
Fill in the blank: The unit of mass in the International System of Units (SI) is the _____ .
kilogram
True or False: Weight can be measured using a scale.
True.
What is the gravitational field strength on the Moon compared to Earth?
The gravitational field strength on the Moon is about 1.6 N/kg, which is approximately 1/6th that of Earth’s.
