Mass versus Weight Flashcards
What is mass?
Mass is the amount of matter in an object.
What is weight?
Weight is a force and is caused by the pull of gravity acting on a mass. Weight
is a vector quantity which means it has both magnitude and direction.
Fact about mass..
Mass is not a force and has the same value anywhere in the Universe, including
outer space.
Facts about weight..
Weight has different values depending on where the object is in the Universe.
What is gravity?
Gravity is the force that attracts objects with mass towards each other.
Facts about gravity..
The bigger the mass of the object, the stronger the force of gravity.
What can gravitational pull be called?
gravitational field strength.
Formula for weight?
weight=mass x gravitational field strength
W=m x g
What is weight measured in?
Newtons
What is mass measured in?
Mass is measured in kilograms
What is gravitational field strength measured in?
Newtons per kilogram
N/Kg
What is the gravitational field strength in earth?
10 N/Kg
Formula for gravity
