Mass And Weight Flashcards
What is the definition of mass?
The amount of matter in an object, measured in kilograms (kg) or grams (g)
Mass tells you how much ‘stuff’ is inside the object and never changes regardless of location.
What is the definition of weight?
The force with which an object is pulled toward the center of a planet or moon due to gravity, measured in newtons (N)
Weight depends on both the mass of the object and the strength of gravity at a specific location.
True or False: Mass changes depending on where you are in the universe.
False
Mass remains constant regardless of location.
What equation is used to calculate weight?
Weight = Mass × Gravitational Field Strength
This equation shows that weight increases with greater mass.
What is the gravitational field strength on Earth?
Approximately 9.8 N/kg
This value is used to calculate the weight of objects on Earth.
If an object has a mass of 10 kg, what would its weight be on Earth?
98 N
Calculated using the formula: Weight = 10 kg * 9.8 N/kg.
Fill in the blank: The weight of an object changes in different parts of our solar system because _______ is different on each planet.
[gravity]
Different planets have different gravitational strengths, affecting weight.
What is the gravitational field strength on Mars?
About 3.7 N/kg
This is much weaker than the gravitational field strength on Earth.
Distinguish between mass and weight.
Mass is constant; weight can change depending on gravity
Mass measures matter; weight measures the force due to gravity.
In what units is weight measured?
Newtons (N)
Weight is a force and therefore is measured in units of force.
What happens to your mass when you travel to the Moon?
It remains the same
Your mass does not change regardless of location in the universe.
